4 Summary

Some basic parameters of the considered galaxies are collected in Table 2. Its lines contain: (1) -- the standard major and minor diameters of the galaxy from the RC3; (2) -- the total apparent magnitude; (3) -- the adopted value of galactic extinction; (4) -- the radial velocity with respect to the centroid of the Local Group; (5, 6) -- the mean magnitude and mean colour of the three brightest blue stars; (7, 8) -- the photometric distance modulus and corresponding linear distance; (9) -- the absolute magnitude of the galaxy.

As one can see from these data the radial velocities of all 5 galaxies lie in the narrow interval: [+250, +350] km/s. At the same time their photometric distance estimates differ by more than a factor 3. Apparently, this indicates significant peculiar (non-Hubble) motions inside the Canes Venatici cloud. We intend to discuss the kinematics of this nearby complex when the program of measurements of individual distances to galaxies in CVn is completed.
