Description:
The central region of the Centaurus cluster was surveyed on a film
copy of a high-resolution photographic Las Campanas duPont plate. A
large number of cluster galaxy candidates were identified down to a
limiting magnitude of 21.5 in B. Between cluster members and
background objects were distinguished by applying morphological
criteria. Following the morphological classification of each member,
the images of all 296 cluster galaxies on a SERC deep-blue sky survey
plate were digitized, processed and analysed with the image processing
package MIDAS. We established total apparent B-magnitude and other
structure parameters for each cluster galaxy which are listed in the
Centaurus Cluster Catalogue.
