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 catalog using objective criteria. A preliminary comparison of physical properties in these two samples reveals that galaxies in high-density environments tend to be under a higher starbursting activity, have a deficiency of the neutral hydrogen content, present a higher fractional Seyfert population and a higher fraction of barred spirals as well. The present samples are intended to be used in future spectroscopic observations for more detailed investigation.
