Description
We have digitally coadded APM scans of 13 Kodak TechPan films of the SE
region of the Virgo Cluster of galaxies. The ~6.2°×6.2°
field of the R-band films combined with the resolution of ~2 arcsec
pixel^- results in data-file sizes of about 222 MBytes. The 13 scanned
films have been aligned, coadded, corrected for vignetting effects and
cleaned of stellar features. To illustrate the astrophysical uses of
this technique, we present high-contrast images of a sample of
interacting galaxies in the field. Several very faint features (but very
clearly seen in the coadded array) - such as the interaction between IC
3481, IC 3481A and IC 3483, and NGC 4410A and B and IC 790 - have been
presented with clarity for the first time.
