| dc.description | We compiled an all-sky catalog of 451 nearby galaxies, each having an individual distance estimate $D \la 10$ Mpc or the radial velocity $V_{LG} < 550$ km s$^{-1}$. The catalog contains data on basic optical and HI properties of the galaxies: their diameters, absolute magnitudes, morphological types, optical and HI surface brightnesses, rotational velocities, indicative mass-to-luminosity and HI mass-to-luminosity ratios, as well as a so-called "tidal index", which quantifies the galaxy environment. We expect the catalog completeness to be $\sim75$% within 8 Mpc. About 85% of the Local volume population are dwarf (dIrr, dIm, dSph) galaxies with $M_B>-17.0$, which contribute about 4% to the local luminosity density, and $\sim(10-16)$% to the local HI mass density. We found that the mean local barion density $Ω_b(<8$ Mpc) = 2.3% consists of only a half of the global barion density, $Ω_b=(4.7\pm0.6)$% (Spergel et al. 2003). The mean-square pairwise difference of radial velocities is about 100 km s$^{-1}$ for spatial separations within 1 Mpc, increasing to $\sim 300$ km s$^{-1}$ on a scale of $\sim 3$ Mpc. | |
