Table information for 'smakced.main'
General
Table Description:
SMAKCED infrared images and derived properties of early-type dwarf
galaxies in the Virgo cluster.
This table is
available for
ADQL queries and through the
TAP endpoint.
Resource Description:
The Stellar content, MAss and Kinematics of Cluster Early-type Dwarf
galaxies (SMAKCED) project is a survey of 121 Virgo cluster early type
galaxies. This service publishes deep near-infrared (H band) images
obtained by SMAKCED together with resulting decompositions and other
properties of the galaxies in the sample.

Resource Documentation
The images are calibrated such that
mag_H = -2.5 log(counts)
(in the 2MASS photometric system) without the need for an
additional zeropoint. Extinction correction according to
1998ApJ...500..525S is already applied to these values.
