The Arizona-New Mexico Spectroscopic Survey of Galaxies. III. On Galaxy Populations
We examine the population statistics for two samples of galaxies in thedirection of the Perseus supercluster. One sample, with N=258 galaxieshaving MB<=-19.52+5log(h) and vh<=8000 kms-1, is complete for those galaxies within the boundaries ofour survey region that have apparent magnitudes mp<=15.0in the Zwicky catalog. A more restrictive sample with N=177 galaxieshaving MB<=-20.00+5log(h) (with the same redshift range)is complete in both luminosity and volume. We derive the statistics forthe relative incidence of galaxies in the following spectroscopicclasses: (1) absorption line only, (2) collisionally-excited emissionlines only, (3) nuclear H II region, (4) starburst, (5) LINER, and (6)Seyfert 1.8-2.

The Arizona-New Mexico Spectroscopic Survey of Galaxies. I. Data for the Western End of the Perseus Supercluster
We present new optical spectroscopic data for 347 galaxies in the regionof the Perseus supercluster. The new data were obtained using theSteward Observatory 2.3 m telescope and cover the whole optical window.Included are redshifts (for 345 objects), absorption-line equivalentwidths, a continuum index measuring the 4000 Å break, andemission-line flux ratios. After 11 objects are rejected for being toofaint and redshifts for 26 objects are added from the literature, wearrive at a complete sample of 361 galaxies. The distribution ofredshifts for the whole sample is examined, and we show the relationshipof the continuum index to morphology.

A 21 CM survey of the Pisces-Perseus supercluster. IV - Addenda to the declination zone 21.5 deg to 33.5 deg
Using the 305-m Arecibo telescope, 21-cm line data on 472 disk galaxiesin the Pisces-Perseus supercluster have been obtained. Data on galaxiessmaller than 1 arcmin are presented for the declination strips coveredin previous studies (Giovanelli and Haynes, 1985 and Giovanelli et al.,1986). Tables of the 21-cm line data for this region are presented.
