4 Summary

We obtained large scale CCD images in the B, V, R and I bands for six spiral and irregular galaxies with corrected radial velocities in the range of 340-460 km s^-1. All the galaxies are well resolved into stars. Three of them have been resolved for the first time. Based on the luminosity of the brightest blue stars we determine their distances, which are collected in Table 2 together with other integral parameters of the galaxies. All the galaxies are known IRAS sources. Except NGC 5474, the galaxies seem well isolated systems, whose crossing time with respect to their neighbours is comparable with the cosmic expanding time, 1/H. Individual estimates of the Hubble parameter, H= V₀/D, lie in the range of 40-83 km s^-1/Mpc, showing the tendency for a decrease in H with increasing galaxy supergalactic latitude, SGB (the last line in Table 2). This tendency agrees well with the general picture of an anisotropic expansion of the Local volume, which seems slower in the directions of the poles of the Local "pancake'' (Karachentsev & Makarov 1996).
