M/L, Hα rotation curves, and H I measurements for 329 nearby cluster and field spirals. I. Data.


Abstract (from CDS):

A survey of 329 nearby galaxies (redshift z<0.045) has been conducted to study the distribution of mass and light within spiral galaxies over a range of environments. The 18 observed clusters and groups span a range of richness, density, and X-ray temperature and are supplemented by a set of 30 isolated field galaxies. Optical spectroscopy taken with the 200 inch (5 m) Hale Telescope provides separately resolved Hα and [N II] major-axis rotation curves for the complete set of galaxies, which are analyzed to yield velocity widths and profile shapes, extents, and gradients. H I line profiles provide an independent velocity width measurement and a measure of H I gas mass and distribution. I-band images are used to deconvolve profiles into disk and bulge components, to determine global luminosities and ellipticities, and to check morphological classification. These data are combined to form a unified data set ideal for the study of the effects of environment upon galaxy evolution.
