A data base for clusters of galaxies has been created in Toulouse. This will be complementary to existing databases such as NED http://ned.ipac.caltech.edu and the CDS http://cdsweb.u-strasbg.fr 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: http://webast.ast.obs-mip.fr/bax (BAX = Base de donn�es des Amas en rayons X, I guess) Boud
