Description:
A systematic search for disklike edge-on galaxies with a diameter
larger than a=40 arcsec and major-to-minor axis ratio a/b>7 has been
carried out by means of Palomar Observatory Sky Survey and ESO/SERC
survey. As a result, we present new catalog of a flat galaxies (FGC)
containing 4455 objects and covering about 56% of the whole sky for
the first time. The catalog is assigned to study large-scale cosmic
streamings and another problems of observational cosmology.
Due to a better quality of the photographic emulsions used for the
southern sky survey, the galaxies measured on ESO/SERC films extend to
a surface magnitude slightly fainter than the same galaxies measured on
POSS prints. So we present the catalog data separately for northern sky
(DEC from -17.5 to +90 degrees) - FLAT GALAXY CATALOG , FGC, N = 2573
and for southern sky (DEC from -90 to -17.5 degrees) - SOUTHERN
EXTENSION OF FLAT GALAXY CATALOG, FGCE, N = 1882.
There are about 200 galaxies in a common region which were found and
measured independently on POSS prints and ESO/SERC films. They were
included in FGC, not in FGCE. The mean ratio <a(ESO)/a(POSS)> for
them is equal to 1.26+/-0.4. This value is near to the result obtained
by Lauberts (1982). Making some statistics it is easy to exclude FGCE
galaxies with a <50arcsec to have the same depth of the sample.
The Appendix to Flat Galaxy Catalog - Addendum - contains the data of
291 galaxies. They were selected in preliminary survey but rejected
after more precise diameter measurements because of violation the
a/b >= 7 criterion. In every case, these galaxies can be used in
different observational programs.

80 A1 --- Notes [*] A star indicates the presence of a note.
--------------------------------------------------------------------------------
Note on As:
Index of apparent asymmetry:
0 - feebly marked
2 - pronounced
The features of asymmetry may be: - different length of spiral arms,
- symmetry in the luminosity distribution, - resence of bright knots,
- distortion of galaxy shape and so on.
Note on N:
N are the number of significant neighbors having an angular diameter
in the range from 2a to a/2 and located in the circle of R=10a ,
where a is major axis of galaxy considered.
