The Arizona–New Mexico Spectroscopic Survey of Galaxies. I. Data for the Western End of the Perseus Supercluster

Abstract

We present new optical spectroscopic data for 347 galaxies in the region of the Perseus supercluster. The new data were obtained using the Steward Observatory 2.3 m telescope and cover the whole optical window. Included are redshifts (for 345 objects), absorption-line equivalent widths, a continuum index measuring the 4000 A break, and emission-line flux ratios. After 11 objects are rejected for being too faint and redshifts for 26 objects are added from the literature, we arrive at a complete sample of 361 galaxies. The distribution of redshifts for the whole sample is examined, and we show the relationship of the continuum index to morphology.
