Equatorial coordinate system distribution of all the galaxies in the HyperLeda database with measured T and M_B, from top to bottom corresponding to V_CMB< 7000, 10 000, and 14 000 km s^-1. The color code is T, the empty parts are the region around the disk of the Milky Way, the plane of the ecliptic is shown with a dotted line, and the pair of hemispheres with the greatest difference in the distribution of morphologies are divided by a red solid line.
