\begin{abstract}

The authors have used the IRAS data to compile a sample of 893 galaxies,
including 118 Seyfert galaxies. ADDSCAN/SCANPI integrated fluxes at 12, 25, 60,
and 100 microns from the IRAS survey, along with redshifts and 1950 coordinates
are given for all galaxies.

\section{Introduction}

{\em The 12 Micron Galaxy Sample} is an all--sky ($|b|\ge25^{\circ}$) sample of
893 galaxies selected from the {\em IRAS Faint Source Catalog, Version~2}. The
sample is 12--micron--flux--limited at 0.22~Jy and is complete down to a 12\um\
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.  {\bf A copy should accompany
any further distribution of this version of the machine-readable catalog.}

\section {Structure}

\subsection{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--lum 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.

\subsection{File Format}

Table 1 gives a byte-by-byte description of the contents of the data file.

\Large{Notes to Table 1}
\end{center}

RA and Dec are 1950, from the {\em 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.

\section{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\um,
Far--IR, and 60\um\ 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.

(1) Excluded when looking at ADDSCANs, finding charts, and {\em IRAS} colors.

(2) Excluded by {\em 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\um\ 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\um\
flux.
