Another look at the size of the low surface brightness galaxy VCC 1661 in the Virgo Cluster
... We obtained new wide-field imaging that allowed us to re-measure this galaxy’s extent. Thereby, we could con- firm that the characteristic radius (here parameterized by a S´ersic profile) is fully consistent with typical ...
