Summary:
This atlas contains the ultraviolet spectra of the central
regions of 143 spiral, irregular, blue compact, Seyfert 2, and
starburst galaxies, which were produced by combining 387 low resolution
spectra from the International Ultraviolet Explorer (IUE) data archive.
The spectra have been extracted with an optimal algorithm and co-added
to produce spectra with the best possible signal-to-noise ratio. The
holdings for this catalog include three files: One file contains the
atlas spectral data in ASCII format, and two files (ASCII and TEX
format) contain Table 1 from Kinney, Bohlin, Calzetti, Panagia, and Wyse
(1993). Table 1 lists summary information about each galaxy including
the figure number, galaxy name, morphological type, activity class,
recession velocity, apparent magnitude, absolute magnitude, E(B-V),
galactic longitude and latitude, right ascension, declination and other
names. For each galaxy the atlas spectral data file contains the
following columns: wavelength, IUE quality flag (Epsilon), gross flux,
background flux, net flux divided by exposure time, absolute calibrated
net flux, exposure time, and sigma. The atlas spectral data file
consists of 177600 78-byte records and the ASCII version of Table 1
has 143 146-byte records.

Description:
This catalog contains the co-added spectra from "An Atlas of
Ultraviolet Spectra of Starforming Galaxies" (AUVSSG). Data for this
atlas were obtained from the IUE archives and include spectra from the
short wavelength prime (SWP, camera 3), long wavelength prime (LWP,
camera 1), and long wavelength redundant (LWR, camera 2) cameras. Only
large aperture (10 arcsec x 20 arcsec rectangular slit) spectra were
used.
An optimal extraction technique was used to extract the spectra from the
spatially resolved IUE data. See Kinney et al. (1991a) for a
discussion of the optimal extraction technique and AUVSSG for a
discussion of the extraction and calibrations used in this atlas. A
previous atlas of Kinney et al. 1991b was also generated using
similar techniques. Note that the archival data for this
catalog were processed with the IUE Spectral Image Processing System
(IUESIPS) (Turnrose and Thompson 1984).
Structure:
The Files as a Whole
The holdings for "An Atlas of Ultraviolet Spectra of Starforming
Galaxies" consist of three files. Two versions of Table 1 from AUVSSG
are available. One version is in TEX format. A second ASCII format
version of Table 1 is contained in a single fixed-block file
of 143 146-byte records. The atlas spectral data are contained
in a single fixed-block file of 177600 78-byte records.
Detailed descriptions of some of the fields in the files are given in
the following sections.

Notes on name*, RA*, DE*, GLON, GLAT, MType:
The names, cross-identifications, coordinates, and some of the
morphological types are taken first from RSA or from the
literature, and otherwise come from the NASA Extragalactic
Database (NED). The morphological type follows, where possible, the
classical Hubble classification. Specific symbols are Am. = amorphous,
Comp. = compact, Cl. Irr. = clumpy irregular, 2-nuc. = presence of
two nuclei.
Note on E(B-V), class, ref :
The reddening E(B-V) from our Galaxy is from Burstein, D.
and Heiles, C. 1984, ApJ Supp., 54, 33. The activity classification is
as follows: BCG and BCDG are, respectively, blue compact galaxies and
blue compact dwarf galaxies (where a blue compact galaxy is considered
to be a dwarf if it has MB fainter than -20); Sy2 are Seyfert 2
galaxies; SB nuc. are galaxies experiencing a starburst in their
nuclei; Hs are hotspot galaxies; Lin are LINERs; HII are galaxies with
spectra typical of an HII region.
The criterion for defining the class is not based on physical
considerations but comes from the literature, where the most widely
accepted classification has been used for each galaxy. The first column
gives the figure number for galaxies treated individually in this paper.
If no figure is given, a reference for the activity classification is
given as listed below:

Note on vH, BT, MB:
The recession velocity (vH) and the apparent magnitude (BT) are from
"The Revised Shapley-Ames Catalogue" when no marks are shown; vH is the
heliocentric velocity; BT is the apparent magnitude in the BT system
of the RC2 ("Second Reference Catalogue of Bright Galaxies"); MB is the
absolute magnitude calculated from an apparent magnitude corrected for
galactic and internal absorption and from a recession velocity reduced
to the centroid of the Local Group (cfr. RSA).
Note on Note_1, Note_3, Note_4:
Note 1, Note 3, and/or Note 4: An asterisk following a value of
vH, BT, or MB means the following: vH and BT correspond to the
heliocentric velocity and to the uncorrected apparent magnitude
from "The Third Reference Catalogue of Bright Galaxies" (RC3); vH is
the V21 or the Vopt when the first is not available (the difference
between the two is in general small). The absolute magnitude MB is
obtained from RC3 using the velocity reduced with respect to
the Galactic Standard of Rest, vGSR, the apparent magnitude
corrected for galactic and internal absorption, BoT, and assuming
H0 = 50 km/s/Mpc. For recession velocities between 500 and 3000 km/s
MB has been calculated with the usual formula after checking that it is
not near a cluster. For v > 3000 km/s the formula has been applied
without problem. Redshift corrections were applied for v > 10,000 km/s.
For galaxies belonging to a cluster MB has been obtained from
BoT (RC3) and with the assumed distance being the distance of the
cluster.
Note on Note_2, Note_5:
Note 2 and/or Note 5: Other notation is as follows: p-When BT is
not available from RC3, the photographic magnitude has been reported;
o-This marks galaxies with redshift in the range 500-3000 km/s, but not
belonging to a cluster; m-This marks the distances calculated through
the distance modulus; a-BT or corrections to derive BoT have
been taken from r1; b-BoT have been taken from r2; c-Galaxies for
which BT or vH or both have been taken from NED since they are not
reported in RSA or in RC3; the same values have been used to calculate
an approximate value for MB. The symbol indicates also an approximate
MB for galaxies with both vH and BT from RC3 but without the
extinction corrected BoT.
Spectral Atlas File
The information for each galaxy consists of a header plus the co-added
spectra and is separated from the next object by a blank line (record)
of 78 bytes. Each co-added spectrum is preceeded by a header containing
the object number, object name, IUE camera(s), and image number(s)
that were used to form the co-added spectrum. A sample header is given
below. The first line contains the target number and the object name.
The next line gives the total number of individual spectra that were
used to form the co-added spectrum from the SWP (camera 3) camera. The
next four lines give the individual image number(s) of the spectra, used
to form the co-added SWP spectrum. Note that the S-AP nomenclature
indicates the spectra are normalized in flux to the L-AP set of spectra
and does NOT mean that the spectra were obtained in the small aperture.
A second group of five lines may also be given in the header
for the long wavelength camera (either the LWP [camera 1] or LWR
[camera 2]). The first byte in each line (record) in the header is
blank. In the example below only one large aperture SWP and one large
aperture LWP image were used to form the spectrum of 1050+04.

History:
Remarks and Modification
"An Atlas of Ultraviolet Spectra of Starforming Galaxies" was
received by the Astronomical Data Center (ADC), NASA Goddard
Space Flight Center, from Dr. Anne Kinney, Space Telescope
Science Institute, Baltimore, Maryland.
The spectral data for each of the objects were originally contained in
143 separate files. These files were first concatenated into a single
file by the data center. The headers for each of the objects were then
edited to remove information that was relevant only to the original tape
versions of the data (i.e., record and file numbers) and not relevant to
the ADC on-line version. Some redundant information was also removed
from the headers to make them more readable. The position of fields 6,
7 and 8 (absolute net flux, exposure time, and sigma) varied by 1 byte
from object-to-object in the original data files. The information in
these three fields were shifted by 1 byte to the right so that all
entries were aligned vertically. The affected object numbers
were 1, 4, 5, 11-13, 17, 21, 29-30, 32-36, 39-40, 42-44, 48-49,
51-56, 58-59, 61-64, 68-79, 81-86, 88-92, 94-108, 110-114, 116-117,
120-132, 134-135, 140-142. The epsilon and net flux/time fields were
edited to align the sign bytes into the same column for each respective
field.
Table 1 was received from Dr. Anne Kinney in TEX format and was
converted to ASCII format by the data center using "dvi2tty" and by
realigning the various columns. Documentation within the TEX version of
Table 1 (i.e., Notes to Table 1) is included in this ADC document.
The galactic longitude of NGC3125 was changed from 365.3 (as it was in
the original paper) to 265.3 in the ASCII and TEX versions of Table 1
by the ADC.
Cast in ReadMe format May 1995.
