M31 Globular Clusters

Revised Bologna Catalogue of M31 globular clusters and candidates: RBC

(V.4, December 2009)

This catalogue will be updated regularly and maintained in electronic form for widest possible accessibility.

!!!!! Please read these notes: !!!!!

The dataset lists all the confirmed GCs, all the known candidates GCs, AND ALSO all the objects that were identified as candidate GCs in the past and were subsequently recognised not to be genuine clusters, each entry being properly classified (GC, candidate GC, foreground star, background galaxy, HII region, etc.). The latter entries are maintained in the catalogue to avoid re-discoveries of objects that may look like M31 GCs and have been already classified as non-GCs.

Please take into account the classification flag(s) when you use the RBC.

Tables including all kind of objects (GCs, GC candidates, galaxies, etc.)

What's new in the RBC V.4 (see Updates & Revisions, above, for details):

·        Revised coordinates (old values from ancient lists have been replaced with 2MASS, GSC-II, etc. coordinates)

·        New candidates GC from Beccari et al. 2007A&A...476..193B have been included

·        Reddening values from Fan et al. 2008MNRAS.385.1973F have been included

·        New classifications from various sources, including Caldwell et al. 2009AJ....137...94C, Perina et al. 2009A&A...507.1375P web-page: HST/ACS colour-magnitude diagrams of M31 globular clusters, Perina et al. 2010 A&A...511A..23P

Warning: Read the note concerning the Caldwell M31 GCs catalogue
