VIII/3 An Optical Catalogue of Radio Galaxies (Burbidge+ 1979)
================================================================================
An Optical Catalogue of Radio Galaxies
Burbidge G., Crowne A.H.
<Astrophys. Journ. Suppl. 40, 583 (1979)>
=1979ApJS...40..583B
================================================================================
ADC_Keywords: Galaxies, radio; Redshifts; Radio sources; Galaxy catalogs
Description:
This catalog contains basic optical information on all known radio
galaxies (with L[radio] greater than about 10**[41] ergs/s) that had
been identified as of 1979 and for which measured redshifts were
available. The data include the right ascension and declination
(1950); galaxy (optical) type; visual magnitude; photoelectric colors;
redshift (z) and the spectral lines on which the redshift measurements
were based; coordinate designations; radio flux and frequency; radio
spectral index; other names; and the references for the galaxy
identification, photometric data, redshift, radio flux, radio spectral
index, and radio map number. Note that the ADC version of this catalog
differs somewhat from the original printed catalog in that some fields
were added or modified and other fields reordered. In addition to the
catalog data file itself, two additional files containing the list of
references for the catalog are also available. The first reference
list is in alphabetical order, and the second is in numerical order.

--------------------------------------------------------------------------------
Note on q_RAs:
Precision indicator of the right ascension; the right ascension is
given as HH MM SS.ss with eight possible significant digits. The
precision indicator identifies how many of these eight digits are
given as blank (i.e. not known) and so may vary between zero and
eight.
Note on q_DEs:
Precision indicator of declination: the declination is given as DD MM
SS.S with seven possible significant digits. The precision indicator
identifies how many of these seven digits are given as blank (i.e. not
known) and so may vary between zero and seven.
Note on EqPos:
Code for equatorial position:
blank = optical position given taken primarily from papers reporting
the redshift and identification papers.
R = radio position given ("*" in published catalogue).
Note on OptType:
Optical type code - left justified in field. The type codes and their
statistics are given in "Table A-2" section below. All types and
cluster information (cf. bytes 38-39) is drawn from either the
identification reference (cf. bytes 25-27) or the redshift reference
(cf. bytes 81-83).
Note on Rdesc:
Radio description which is no longer used. If these bytes are not
blank then given object is in a cluster. The radio description codes
and their statistics are given in "Table A-3" section below.
Note on Vmag:
Visual magnitude. These values are very uncertain since very few
photometric measurements have been made.
Note on Z:
Redshift. Most of the redshifts listed are uncorrected for galactic
rotation.
Note on n_Z:
Redshift (cf. bytes 63-68) qualifier:
blank - if the value of the redshift (z) is not corrected for galactic
rotation.
"C" - if z is corrected ("*" in published catalogue)
"Q" - if unknown if z has been corrected ("?" in published catalogue).
Note on LineType:
Spectral lines type:
"A" - if absorption lines.
"E" - if emission lines.
"AE"- if absorption and emission.
Where no spectral-line lists have been published but mention has been
made of the appearance of absorption or emission, it is noted with an "A"
or "E" in these bytes.
Note on Name:
Coordinate designation given as HHMMSDDX based on equatorial coordinates
at epoch B1950.0 where:
HH = hours of right ascension
MM = minutes of right ascension
S = sign of the declination
DDX= declination (unit=0.1deg)
Note on Sp-Index:
Radio spectral index between 408 and 1400 MHz. The spectral index
alpha is defined by
S(nu) = K. nu**(-alpha)
In the published catalogue the symbol ">" following the value of the
spectral index indicates a range between 408 and 5000 MHz and the
symbol "<" indicates a range between 178 and 408 MHz. No attempt has
been made to extrapolate where fluxes have been given at other
frequencies (cf. byte 115).
Note on SIcode:
Code for spectral index range. This code is for the symbols ">" and
"<" as defined above in bytes 102-106. The ">" is coded as an "A" and
the "<" is coded as a "B". This byte is blank if other than these two
spectral indices. See the file "refs".
Note on SpNum:
Number of spectral lines used in the computation of the value of the
redshift. This number ranges from 0 to 20.
Note on Lines:
List of 20 coded spectral lines.
The coded values range from 01 to OR and are defined in
"Table A-4" section below. The N (cf. bytes 116-117) coded values are
at the beginning of this field and the remaining bytes are blank.
Note on Arefs:
Additional references are five characters each where the first three
represent the reference number (file "refs") and the two letter code
for the type of reference as follows:
ID - identification
FC - finder chart
Z - redshift
S - radio flux (S)
SI - radio spectral index (SI)
M - radio map
Note on Alias:
Other names - maximum of seven names separated by commas with no
embedded blanks. "Table A-1" section below gives the codes used in
these fields along with their full reference to the published
literature.

the hours of right ascension, the first digit gives
the declination in 10degrees increments, and the last two
digits give the right ascension to 0h01 (thus OQ 172
has 10deg < delta < 20deg and alpha = 14.72h).

NB. C5 was defined as Abell 779 in the original documentation
for this catalogue, but this code was not found for any of
the records. However, since the first data card for #154
(coordinate designation 0812-029) was missing, this could
account for the discrepancy. This particular galaxy was
counted in.the blank code. Since this piece of datum does
not appear in the published catalogue there was no way to
identify what the radio description code should have been.

History:
* Summer 1981, at NASA/Goddard Space Flight Center:
The machine-readable version of the Optical Catalog of Radio Galaxies
(Burbidge and Crowne 1979) was received at NASA/Goddard Space Flight
Center (NASA/GSFC) from one of the authors (Adelaide Hewitt, formerly
A. H. Crowne) in the summer of 1981.
Extensive modifications to the format of the machine-readable
catalogue have been made. Originally the magnetic tape consisted of
card image records on one file which contained the data (five cards
per entry) followed by the references. This single file has been
divided into two separate files: a data file and a reference file.
There are 495 data records and 412 reference records each on a
separate file. In addition, the reference file is sorted numerically
to generate the three file magnetic tape described herein.
The numbers which quantitatively define the precision of the
components of the equatorial coordinators have been computed and added
to the records to readily identify less precise coordinate
availability. Information in byte 24 of the original first data record
was moved to byte 28 to add the computed precision indicator for the
declination. The coordinate designation, which is the key identifier
in the published catalogue, was computed from the given coordinates
and added to each record (cf. bytes 73-80) since it was not originally
given on the tape for the majority of the records. The number of
spectral lines present and the number of additional references have
been computed for each record and added (cf. bytes 116-117 and 158-159
respectively in file "refs". One object (#154, 0812-029) had the first
of the five data cards missing. The data have been reconstructed from
the published catalogue whenever possible. There are several data
items that are given in the machine-readable version of the catalogue
that are not in the published catalogue and so the values of these
were not reconstructed for the missing data record. The radio
description (cf. bytes 38-39, file "catalog") is given in the
machine-readable version with the note that it is no longer used, but
not in the published catalogue. The photometric colors (B-V) and (U-B)
are given for very few of the entries in the machine-readable version
but also do not appear in the published catalogue. This is also true
of the photometric reference for the data values. The frequency (MHz)
is another quantity that appears in the digital version of the
catalogue but not in the published version. Embedded blanks have been
removed from the other names field and commas have been added to
separate entries. A sequential counter (range 1 to 495) was added to
each data record. The record preceding the references on the original
tape contained the number 411 (actually there are 412 references) and
was removed. In addition, the last record was a "999" to designate the
last card image record was removed.
Some references were on a single card image and some continued onto a
second card image. The information has been joined together into a
single record of equal length for each reference. The counter in the
reference file was also inconsistent where some had leading zeros and
others did not, and some had the period (".") following the number and
others did not. The file that has been produced is consistent in these
matters and is defined in file "refs" of this document.
Table A-1 is a list of the many designations used in the other names
field (cf. bytes 220-269, file "catalog") and the full reference for
each. This table was prepared utilizing the information in the
published catalogue.
Tables A-2 and A-3 respectively represent statistics compiled during
the preparation of this document. The statistics are for the counts of
coded optical types and radio descriptions respectively.
Table A-4 is information originally supplied by the authors and
provides the code for spectral lines used in the determination of the
redshift (z) value. The user of this catalogue is advised to use the
other identifier correspondences available in the published catalogue
whose reference is given below.
* June 1993: modifications at CDS (F. Ochsenbein):
The printed document was used as input for the present documentation.
A few misalignments in the file "catalog" have been corrected in records
("Seq") numbers 2, 20, 114, 132, 154, 202, 237, 240, 251, 263 and 428
