Table information for 'pcc.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This is a catalog of 5437 morphologically classified sources in the direction of the Perseus galaxy cluster core, among them 496 early-type low-mass galaxy candidates. The catalog is primarily based on V-band imaging data acquired with the William Herschel Telescope. Additionally, we used archival Subaru multiband imaging data in order to measure aperture colors and to perform a morphological classification. The catalog reaches its 50 per cent completeness limit at an absolute V-band luminosity of -12 mag and a V-band surface brightness of 26 mag arcsec^-2 . In addition to the published table, this service also contains cutout images of the objects investigated.
