Abstract
We present a new version of a sample of galaxies from the Revised Flat Galaxy Catalogue (RFGC), which have redshift and H i line width data. We also give the parameters of the collective motion model determined upon this sample. The considered models of motion include the dipole (bulk flow), the quadrupole (cosmic shear) and the octupole components. We also considered higher-order multipoles. In all cases the obtained parameters matched the ΛCDM cosmology.
