Resource Description:
For a list of all services and tables belonging to this table's resource, see Information on resource 'A Catalog of Galaxies in the Direction of the Perseus Cluster'
This table has an associated publication. If you use data from it, it may be appropriate to reference 2019ApJS..245...10W (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:pcc_main, year=2019, title={A Catalog of Galaxies in the Direction of the Perseus Cluster}, author={Wittmann, C. and Kotulla, R. and Lisker, T. and Grebel, E.K. and Conselice, C.J. and Janz, J. and Penny, S.J.}, url={https://dc.zah.uni-heidelberg.de/tableinfo/pcc.main}, howpublished={{VO} resource provided by the {GAVO} Data Center} }
