Table Description:
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.
For a list of all services and tables belonging to this table's resource, see Information on resource 'A Near-infrared Census of the Multicomponent Stellar Structure of Early-type Dwarf Galaxies in the Virgo Cluster'
This table has an associated publication. If you use data from it, it may be appropriate to reference 2014ApJ...786..105J (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.
To cite the table as such, we suggest the following BibTeX entry:
@MISC{vo:smakced_main, year=2014, title={A Near-infrared Census of the Multicomponent Stellar Structure of Early-type Dwarf Galaxies in the Virgo Cluster}, author={Janz, J. and Laurikainen, E. and Lisker, T. and Salo, H. and Peletier, R. F. and Niemi, S.-M. and Toloba, E. and Hensler, G. and Falcón-Barroso, J. and Boselli, A. and den Brok, M. and Hansson, K. S. A. and Meyer, H. T. and Ryś, A. and Paudel, S.}, url={http://dc.zah.uni-heidelberg.de/tableinfo/smakced.main}, howpublished={{VO} resource provided by the {GAVO} Data Center} }
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.
