Scientific paper

Based on photometry of the brightest blue stars we derived distance moduli for NGC 628 and its dwarf irregular companions: DDO 13, UGC 1171, UGC 1104, and K 10. The mean modulus of the group is estimated to be 29.46 mag with a formal (internal) error of 0.11. The total mass to luminosity ratio of 40M&sun;/L&sun; seems sufficient for NGC 628 to keep its companions in bound orbits. (9 data files).
