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.
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.
