GALAXY PROPERTIES IN DIFFERENT ENVIRONMENTS .1. THE SAMPLE

This paper presents two galaxy samples, respectively in a high and in a low local density environments, that were generated from the SSRS ca talog using objective criteria. A preliminary comparison of physical p roperties in these two samples reveals that galaxies in high-density e nvironments tend to be under a higher starbursting activity, have a de ficiency of the neutral hydrogen content, present a higher fractional Seyfert population and a higher fraction of barred spirals as well. Th e present samples are intended to be used in future spectroscopic obse rvations for more detailed investigation.
