The Arizona-New Mexico spectroscopic survey of galaxies. III. On galaxy populations

摘要

We examine the population statistics for two samples of galaxies in the direction of the Perseus supercluster. One sample, with N = 258 galaxies having M-B less than or equal to -19.52 + 5 log (h) and v(h) less than or equal to 8000 km s(-1), is complete for those galaxies within the boundaries of our: survey region that have apparent magnitudes m(p) less than or equal to 15.0 in the Zwicky catalog. A more restrictive sample with N = 177 galaxies having M-B less than or equal to -20.00 + 5 log(h) (with the same redshift range) is complete in both luminosity and volume. We derive the statistics for the relative incidence of galaxies in the following spectroscopic classes: (1) absorption line only, (2) collisionally-excited emission lines only, (3) nuclear H II region, (4) starburst, (5) LINER, and (6) Seyfert 1.8-2.
