Abstract
The authors have used the IRAS data to compile a sample of 893
galaxies, including 118 Seyfert galaxies. ADDSCAN/SCANPI inte-
grated fluxes at 12, 25, 60, and 100 microns from the IRAS survey,
along with redshifts and 1950 coordinates are given for all
galaxies.
1 Introduction
The 12 Micron Galaxy Sample is an all-sky (b greater than or equal
to 25 deg.) sample of 893 galaxies selected from the IRAS Faint
Source Catalog, Version 2. The sample is 12-micron-flux-limited at
0.22 Jy and is complete down to a 12mu flux of 0.30 Jy. It
includes 55 Seyfert 1 galaxies (including QSOs and two blazars),
63 Seyfert 2 galaxies, 38 high-far-IR-luminosity non-Seyferts, and
29 LINERs. The flux densities presented are whole-galaxy fluxes
obtained by the ADDSCAN/SCANPI process at IPAC. Observed radial
velocities, mostly obtained from well-known extragalactic catalogs
are also given.
This document is intended to provide the information necessary to
describe this catalog to a computer and to make it easy to use. A
copy should accompany any further distribution of this version of
the machine-readable catalog.

3 Structure
3.1 File Structure
The file given here has 893 lines with 76 bytes of data each. The
data given are exactly the same as those found in tables 1-5 of
the source reference (hereafter RMS), with two exceptions: (1) In
RMS, tables 1-5 represent Seyfert 1s, Seyfert 2s,
high-far-IR-luminosity non-Seyferts, LINERs, and normal galaxies,
respectively, whereas all galaxy types here are in the same table,
sorted by RA; (2) several flags are given, one of which indicates
the galaxy type and, thus, the table in which it would appear in
RMS.

Notes to Table 1
RA and Dec are 1950, from the IRAS Faint Source Catalog, Version
2. (A few exceptions are explained in RMS.)
Flux densities are obtained by the ADDSCAN/SCANPI process at IPAC
for most objects; the exceptions are explained in RMS.
Names and redshifts are taken from various extragalactic catalogs.
Object type is as follows: 0, 1, 2, 3, or 4 for normal, Seyfert 1,
Seyfert 2, high-far-IR-luminosity, and LINER galaxies,
respectively. (How these objects are defined/identified is
explained in RMS.)
Redshift type is as follows: "S" if corrected for solar motion
about the galactic center, and for the Galaxy's motion towards
Virgo; "V" if NOT corrected.
Redshift reference is listed in RMS, but a different labeling
scheme is used here, as given below.

4 Additional Information
In addition to tables 1-5, which contain the data described here,
there are seven more tables of data in RMS. Tables 6-8 therein
give the calculated 12 mu, Far-IR, and 60 mu luminosity functions,
respectively. These three tables are short enough that it would be
easy for those interested in using the actual data to simply type
them in from RMS. Tables 9-12 list various objects that met the
search criterion of the sample, but were excluded for various
reasons (e.g., being galactic objects). These four tables are
given in tables 2-5 in this document.

Notes to Table 3
(1) Optical spectrum of stars
(2) Associated with MCG-2-12-42; optical spectrum contaminated by
a strong late-type star; infrared fluxes contaminated by a nebular
object 3 arcmin SE of the FSC-2 positionl.
(3) stellar-like optical spectrum, infrared fluxes dominated by a
galactic object.

Table 4: Galaxies Excluded
Notes to Table 4
(1) Excluded when looking at ADDSCANs, finding charts, and IRAS
colors.
(2) Excluded by IRAS colors and finding chart; the object itself
is likely a star.
(3) Excluded because an optical spectrum (Lick 1m tel.) and
near-IR photometry (San Pedro Martir Obs., Mexico) showed the
12 mu flux to be mostly from the very red M star just E of the
galaxy.
(4) ZCAT association and SAO association are both within 1 arcmin.
SAO119793 at center, mostly covering the galaxy.
(5) ZCAT association and SAO association are both within 1 arcmin.
The galaxy is closer to the center, but SAO129652 appears large
and is touching the galaxy just to the right.
(6) Excluded because, upon viewing the finding chart and ADDSCANs
two clearly separated galaxies are each contributing less than
0.20 Jy of the 12 mu flux.

Table 5: Unidentified Objects
Notes to Table 5
(1) Somewhat suspicious [25-12] color for a galaxy. It appears
slightly extended in the optical plates. It can be either a galaxy
or a star with some nebulosity.
(2) Very suspicious IRAS colors for a galaxy. It is located within
the boundaries of the SMC, but not identified by Schwering and
Israel (1989).
(3) IRAS colors consistent with being a galaxy.
