Abstract:
We have identified in the 2MASS database 693 known and candidate
globular clusters in M31. The 2MASS J,H,K magnitudes of these objects
have been transformed to the same homogeneous photometric system of
existing near infrared photometry of M31 globulars, finally yielding
J,H,K integrated photometry for 279 confirmed M31 clusters, 406
unconfirmed candidates and 8 objects with controversial
classification. Of these objects 529 lacked any previous estimate of
their near infrared magnitudes. The newly assembled near infrared
dataset has been implemented into a revised version of the Bologna
Catalogue of M31 globulars, with updated optical (UBVRI) photometry
taken, when possible, from the most recent sources of CCD photometry
available in the literature and transformed to a common photometric
system. The final Revised Bologna Catalogue (table 2) most
comprehensive list presently available of confirmed and candidate M31
globular clusters, with a total of 1164 entries. In particular, it
includes 337 confirmed GCs, 688 GC candidates, 10 objects with
controversial classification, 70 confirmed galaxies, 55 confirmed
stars, and 4 HII regions. Using the newly assembled database we show
that the V-K color provides a powerful tool to discriminate between
M31 clusters and background galaxies, and we identify a sample of 83
globular cluster candidates, which is not likely to be contaminated by
misclassified galaxies.
