Abstract (from CDS):

We present an analysis of Hubble Space Telescope/WFPC2 images of six nearby galaxies in the projected vicinity of IC 342: Cas dSph, KK 35, UGCA 86, Cam A, NGC 1560, and Cam B. We derive distances to five of them from the luminosity of the tip of the red giant branch stars with a typical accuracy of ∼10%. The galaxy distances are 0.79Mpc (Cas dSph), 3.16Mpc (KK 35), 3.93Mpc (Cam A), 3.45Mpc (NGC 1560), and 3.34Mpc (Cam B). Two other observed galaxies, MB 2 and Cam C = KK 26, turn out to be Galactic cirrus and a Galactic HII region, respectively. Cas dSph belongs to the Local Group and is a companion of M31. Combining our data with literature results, we find that there are seven dwarf galaxies associated with the giant spiral galaxy IC 342. This group is characterized by an average distance of (3.28±0.15)Mpc, an average radial velocity of (229±23)km/s, a projected radius of 322kpc, a radial velocity dispersion of 60km/s, and a total blue luminosity of 3.43x1010L. The derived virial and orbital mass-to-luminosity ratios are 20 and 28M/L, respectively. The galaxy group around Maffei 1 has so far a less reliable distance of ∼3.0Mpc and an average radial velocity of (309±22)km/s. This group consists of eight galaxies and is characterized by a projected radius of 112kpc, a radial velocity dispersion of 59km/s, and a total blue luminosity of 2.97x1010L. For the Maffei group we estimate mass-to-light ratios of Mvir/LB=16 and Morb/LB=5 in solar units. The sum of the virial (119x1010M) and orbital (109x1010M) masses of both groups agree well with their total mass, (107±33)1010M, derived from the radius of the ``zero velocity surface'', R0=(0.9±0.1)Mpc, which separates the IC 342/Maffei complex from the Hubble flow.
