FLAT GALAXY CATALOG

A systematic search for disclike edge-on-galaxies with a diameter larg er than a = 40 arcsec and a major-to-minor axis ratio a/b greater-than -or-equal-to 7 has been carried out by means of the Palomar Observator y Sky Survey and the ESO/SERC survey. As a result, we present a new ca talogue of flat galaxies (FGC) containing 4455 objects and covering ab out 56% of the whole sky for the first time. The catalogue is assigned to study large-scale cosmic streamings and other problems of observat ional cosmology.
