Abstract:
    The 2MFGC catalog we have used contains 18020 galaxies selected from
    among the extended objects in the 2MASS infrared sky survey as having
    apparent ratios of the axes b/a<0.3. Most of them are spiral galaxies
    of later morphological types whose disks are seen almost edge-on. The
    individual distances to the 2724 2MFGC galaxies with known rotation
    velocities and radial velocities are determined using a multiparameter
    infrared Tully-Fisher relation. A list of the distances and peculiar
    velocities of these galaxies is presented. The collective motion of
    the 2MFGC galaxies relative to the cosmic microwave background is
    characterized by a velocity V=199±37km/s in the direction
    l=304±11, b=-8±8 . Our list is currently the most representative
    and uniform sample for analyzing non-Hubble motions of galaxies on a
    scale of ∼100Mpc.
