Scientific paper

The observational data base for the Nearby Galaxies Atlas (Tully and Fisher, 1987) and Nearby Galaxies Catalog (Tully, 1988) is analyzed statistically, with a focus on three problems related to the galactic luminosity function (GLF). Sample data are presented in tables and graphs; the GLF is formulated as M(asterisk) = -20.18 + 1.25(1 + alpha) + 5log h(75); and alpha = -1.0 is recommended. An expression for the degree of incompleteness in the catalog is then derived as a function of galaxy distance, and the correlation between galactic morphology and the local density function is explored. It is shown that gas-poor, early-type, and gas-rich galaxies tend to appear in regions of high, intermediate, and low density, respectively. Within the gas-rich subset, however, morphology and luminosity are found to be poorly correlated with density.
