Abstract

We present a sample of galaxies in six fields, each of area 2 sq deg, located in the North and South galactic polar caps. Photoelectrically calibrated photographic magnitudes and J-F colors have been determined for 512 galaxies brighter than completeness limits which range from F = 16.5 to F = 17.2 among the fields. Velocities, with typical accuracies of 150 km s/sup -1/, have been obtained for 280 of the brighter galaxies. Using these data and previously published work, we determine the general galaxy luminosity function parameters to be M(/sub F/ = -22.7, ..cap alpha.. = -1.25, and the mean visual luminosity density of the universe to be rho = 2.3 x 10/sup 8/ h L/sub sun/ Mpc/sup -3/. Assuming M/L/sub v/ = 300h, this implies ..cap omega.. approx. =0.26.
