A data base for clusters of galaxies has been created in Toulouse. This will be complementary to existing databases such as NED
and the CDS
It should contain bibliographic data and published observed properties of clusters, it started in October 2001 (according to the announcement, in French, it started in "October 2002" ;) ) and apparently contains a little more than 1500 clusters of which 1470 have flux measurements and 205 have estimated temperatures.
The cluster database is here:

(BAX = Base de donn�es des Amas en rayons X, I guess)
