Description:
The Catalog of Infrared Observations and its associated data base
comprise a summary of infrared astronomical observations published in
the scientific literature from 1965 through 1997 in the wavelength
range 1 micrometer - 1 mm. The database contains infrared
observational data for sources outside the Solar System, constructed
through a search of the most active scientific journals, IR surveys
and catalogs. To date, about 6200 journal articles and 10 major survey
catalogs have been included in the data base, which contains
374,653 individual observations of about 62,000 different infrared
sources. More than 8,000 of these sources are identifiable with visible
objects. The bibliographical files link observations in the catalog
with the original articles published in the literature. References
give the standard information plus full titles. The Index of Infrared
Source Positions is ordered alphabetically by source name and can be
used to quickly locate sources in the position-ordered catalog. For
sources with no published IR source position, a nominal position may
have been given based on other sources. Nominal positions are usually
the best available, but not necessarily the true IR positions. Nominal
position references are indicated in the index.

Note on catalog.dat:
The data base from which the Catalog of Infrared Observations is
constructed is maintained at the NASA Goddard Space Flight Center.
The Catalog of Infrared Observations has been ordered by increasing
right ascension, then declination, then wavelength of the observation.
The source name used in the originating papers is given. Thus the same
source is often listed under several different names. Sometimes the
same source is listed with multiple positions also.
Please note the following three points.
(1) Sky coverage is not uniform: The catalog data are a mixture of
sky surveys, small-scale region surveys, and numerous individual
source observations. The whole sky has been surveyed only at a few
wavelengths, and then to different levels of sensitivity. Non-survey
observations are not spatially homogeneous.
(2) Data are presented in original published form: No attempt has
been made to create a single system of infrared photometric units, or
to eliminate redundant observations. This kind of interpretation is more
appropriately done by the individual researcher.
(3) The catalog is as accurate as the published data from which it was
constructed: Observations were made by hundreds of investigators,
using different instrumental techniques and methods of analysis.
Differences Between the Machine-Readable and Printed Versions:
Although the printed CIO was produced directly from the Infrared
Astronomical Data Base, there are some minor differences between the
magnetic tape version and the printed version. These changes were
made to clarify the text. The most recent version in print was
the 3rd Edition.
o Dittos are used in the text only, when information on the previous
record is identical with that in the same field for the current
record. All data fields in each record of the tape version contain
data.
o "Nominal" positions (such as the approximate center of a globular
cluster) are indicated differently in the printed and tape versions of
the data base. In the tape version, the first byte of each record
contains an identifier. The first byte does not appear in the printed
version of the CIO.
o The leading zeros for the hours of right ascension and degrees of
declination are explicitly given in the machine-readable copy,
whereas they are omitted in the printed version.
o The abbreviated IRAS Point Source Catalog flux codes are listed in
italics in the printed copy if the flux values given are upper limits.
The machine-readable version uses separate flag fields to indicate
this condition. A separate file lists the IRAS PSC fluxes.
o The position reference has been omitted from all versions in editions 3,
3.4, 4 and 5.
o The bibliographic data for a particular reference are given in two
files. One file has one entry per record with long record lengths, the
other file has entries spread over several records. The spacing,
and duplication of the bibliographic reference number at the end of
the first line of an entry have been changed.
Note on names.dat:
The Index of Infrared Source Positions is a listing of infrared
sources arranged alphabetically by source name. After locating the
name of a source in this index, one can read out its position and then
use this information to quickly find the data for the given object in
the CIO. When published articles do not include the position of the
observed source, the editors provide nominal positions obtained from
other data bases. The nominal positions are the best available, but
in a few cases do not coincide with the true infrared positions. The
source position is given as listed in the CIO at epoch 1950. Sources
without published positions appear in alphabetical order with the
other names and have blanks in the position field.
Note on refauth.dat, refchron.dat, refs.dat:
The Bibliography of Infrared Astronomy links observations in the
catalog with the original articles published in the astronomical
literature. Approximately 6200 infrared articles and other references
are listed in these appendices. The bibliography is arranged
chronologically by reference number and alphabetically by author.
It contains the authors names, journal name or document number,
volume, page, and full title.
The Catalog contains observational data obtained from a search of the
following catalogs and scientific journals for the years 1965-1997,
inclusive. The number of articles in each journal containing infrared
astronomical data and the journal abbreviations used in the
bibliography are indicated in the following table.

Note on spectra.dat:
The Atlas of Infrared Spectral Ranges is a new reference tool
developed from the Goddard Infrared Astronomical Data Base. Since
plotted spectra cannot be easily included in the current automated
data base, this appendix summarizes the wavelength range over which
spectra have been published for individual sources. It lists the
name, starting and ending wavelengths (in microns), and bibliographic
reference number for each published infrared source spectrum. The
object name, starting wavelength, and bibliographic reference number
are as given in the main catalog. The Atlas is sorted alphabetically
by object name with constellation name objects sorted by
constellation. The bibliographic reference number refers to the
original article via files ref*.dat.
Although the inclusion criteria for the Goddard Infrared Astronomical
Data Base specifies a wavelength region of from 1 - 1000 microns, some
catalog entries have wavelengths outside this range. Wavelengths less
than 1 micron indicate that the spectrum starts at this wavelength and
extends into the infrared.
Note on psc.dat:
This file contains data from the Infrared Astronomical Satellite
(IRAS) Point Source Catalog (PSC) (Version 2.0) for those sources
contained in the Catalog of Infrared Observations. The internet
utility XCATSCAN, accessed via telnet to xcatscan.ipac.caltech.edu,
was used to update this information for the years 1996 and 1997.
The full PSC name, position and four-band flux data are given. Upper
limit values are followed by the suffix "U". Moderate quality fluxes
(as defined in the Point Source Catalog) are followed by a colon (:).
About 26,200 individual infrared sources represented in this section of
the CIO were detected in the IRAS Point Source survey. The IRAS 12, 25,
60, and 100 micron fluxes are listed for these CIO sources.
The identification of CIO and PSC sources were based on source
identifications made in the IRAS Point Source Catalog, correlated
infrared source names, and aliases in the Infrared Source Cross-Index
(NASA RP 1182) data base.

Note on edition:
Blank = First edition data
* = First edition nominal position
1 = Second edition data
% = Second edition nominal position
2 = Third edition data from 1987 - 1990
$ = Third edition nominal position from 1987 - 1990
3 = 3D Fourth edition from 1991 or 1995
# = 3D Fourth edition nominal position from 1991 or 1995
4 = data from 1996 - 1997
@ = nominal position for data from 1996 -1997
Nominal positions indicate a general area in the sky.
Note on name:
Object name is left justified. It is common for an astronomical source
to be listed by several different names in the catalog, since the
observations are presented "as given" by the original authors. In
general, source names should be given secondary importance when
searching catalog listings, with positions given priority. Source
names and positions are cross-referenced in the Index of Infrared
Source Positions. Source names are sometimes abbreviated. In some
cases the names are augmented by the editors (for example, when the
original author assigns the source number but no identifying prefix).
Note on RAh,RAm,RAs, DE-,DEd,DEm,DEs:
The accuracy of the positional data in the catalog reflects that of
the data published by the original author. This is true primarily for
visible sources with well-documented positions. In such cases, the
"nominal" source position is entered in the position field by the
editors. When authors omit specific source positions from their
articles, they must presume that the position is common knowledge, to
be found in the appropriate standard catalog. When no such position
can be obtained by the editors, all such entries are sorted
alphabetically by source name and are listed at the end of the
catalog.
Note on beam, x_beam:
The angular beam size of the observation.
Aperture beam units are coded as follows:
S = arcseconds
M = arcminutes
D = degrees
V = 3D several aperture values given in reference
- = no beam size given in original reference
In addition to being a factor in source brightness calculation,
beam size can be used as an aid in determining positional coincidences
and identifications with other sources, and as a first-order indication
of positional accuracy.
Note on lambda:
Wavelength in microns. For spectra the starting wavelength of the
spectrum. Catalog entries having the same celestial position are
listed in order of increasing wavelength. Thus, a rough spectral
distribution appears for each well-observed source position. The units
of wavelength given are micrometers (microns). Note that some entries
have a wavelength range outside the 1 micron-1 mm range. Wavelengths
shorter than 1 micron would indicate that a spectrum exists in the
article starting at this wavelength and extending into the infrared.
A few observations made at wavelengths greater than 1 mm have been
included when the observation was basically done with far-infrared
techniques (some broad-band submillimeter observations). The ending
wavelengths can be found in Appendix A: file spectra.dat.
Note on F(IR):
The infrared flux is listed in the same units as published by the
original observers. The units have been given one- or two-letter
abbreviations (see note x_F(IR) below). Upper limits are flagged in
the n_F(IR) field. To protect the integrity of the data base, no
attempt has been made to convert these different units or infrared
flux into a more homogeneous system. Fortunately, about 95 percent of
the flux observations in the catalog have units of "magnitudes" or
"Janskys," or have comments such as "polarization data," "spectrum,"
etc. An additional 3 percent of the entries are in five other
commonly used units (B,E,F,I,X). The remaining 2 percent of the
entries are in less common units, but which are dimensionally
equivalent to one of the more commonly used units. In general,
infrared magnitudes are calibrated with respect to the flux density of
alpha-Lyr (10,000K BB), which is being defined as 0 magnitude at
all infrared wavelengths (see Gillett et al., 1971, Astrophys. J., 164, 83;
Gertz and Woolf, 1971, Astrophys. J., 165, 185) . The following symbols
sometimes occur in the comments to the IR flux field (n_F(IR)):
V = variable or mean of several values,
L = lower limit (detector saturated),
U = upper limit,
E = editors determined flux from maps, spectra, or other
material in the article presented in non-tabular form. When spectral
data (S) are listed (see x_F(IR)), only the starting wavelength of
the spectrum is given in the "lambda" column. Starting and ending
wavelength of published spectra are given in the spectra.dat file.
Note on x_F(IR):
Infrared flux unit code.
A = normalized magnitude
B = 10-19W/m2/Hz/sr
C = magnitude derived from color
D = diameter measurement
E = erg/s/cm2/sr
F = 10-16W/cm2/um
G = 10-14erg/s/cm2
H = log(ergs/s/cm2/Hz)
I = 10-9W/cm2/um/sr
J = Jy
JA= Jy/arcsec2
K = log(Jy)
L = log(W/m2/Hz)
M = magnitude
MA= magnitudes/arcsec2
N = log(erg/s/cm2/um)
P = polarization data
Q = log(10-3Jy)
R = log(W/cm-2/um)
S = spectral data
T = -2.5log(erg/s/cm2/Hz)-48.60
U = upper limit
V = variable
W = 10-14W/m2
X = 10-18W/cm2
Y = relative line intensity
Z = 10-21W/cm2/um/arcsec2
Note on n_F(IR):
Comments to F(IR), the infrared flux.
E = Flux obtained by the editors
L = Flux value is a lower limit
U = Flux value is an upper limit
V = Flux value is an average value
? = Flux value as published is inconsistent
Blank = no comment
Note on r_F(IR):
The bibliographic reference number identifies the original Journal
article for each observation in the catalog, keyed to the entry in the
bibliographic reference file. The bibliographic reference number is
made up of the year and month of publication, and a randomly assigned
sequential number. In case the publication did not contain infrared
observations an "89" or "99" was assigned as the month of publication.
A "89" means that the reference was published in the nineteenth
century. References that do not indicate the month of publication have
00 in the month field.
Note on IRAS:
IRAS cross identification based on IRAS Point Source catalog V2.0
identifications. Only object ID was checked - not position. Cross-
references are current through 1997.
Note on 12um, 25um, 60um, 100um:
IRAS flux strength code. The strength code is logarithmic as follows:
0 = 0.5-5 Jy
1 = 5-50 Jy
2 = 50-500 Jy
3 = 500-5000 Jy
4 = 5000-50000 Jy
5 = 50000-500000 Jy
For each CIO source detected by IRAS, the corresponding
order-of-magnitude IRAS PSC version 1.0 flux is given using four
digits, one each for the four IRAS bands. The values represent the
approximate logarithm of the flux density. This allows the user to get
an immediate estimate of the IRAS PSC fluxes in a compact format.
Note on q_12um, q_25um, q_60um, q_100um:

Historical Notes:
Version 3.5 was received at the ADC October 1996. The ADC validated
the format of the tables.
The standard document for catalog 2209, the previous edition of the
CIO, was prepared by N. Paul M. Kuin [NASA/ADC] on 24-Oct-1996.
Much of this ReadMe is taken directly from that original document.
P. Pitts provided Version 4 to the ADC November 1997. The table
format was adjusted for alignment (catalog <II/216>)
P. Pitts provided corrections to the ReadMe file on 09-Feb-1998.
Downloaded version 5.0 from
http://ircatalog.gsfc.nasa.gov/cio/ on 21-June-1999.
