Abstract:
An all-sky catalog of 18020 disc-like galaxies is presented. The
galaxies are selected from the Extended Source Catalog of the Two
Micron All-Sky Survey (XSC 2MASS) basing on their 2MASS axial ratio
a/b≥3. The Catalog contains data on magnitudes of a galaxy in
the J, H, Ks bands, its axial ratio, positional angle, index of
luminosity concentration, as well as identification of the galaxy with
the LEDA and the NED databases. Unlike the available optical catalogs,
the new 2MFGC catalog seems to be more suitable to study cosmic
streaming on a scale of z∼0.1. The dipole moment of distribution of
the bright (K<11mag) 2MFGC objects (l=227°, b=41° or
SGL=90°, SGB=-43°) lies within statistical errors (±15°)
in the direction of the IRAS dipole and the optical RFGC dipole.
