This catalogue is based on the one presented in
Pozzo et al (2003
MNRAS 341 805) and
Pozzo (2001; PhD Thesis), with
two significant changes.
1) The formatting now conforms to our normal
cluster format. However,
since "a" and "b" would not fit within that format, the CCDs are
referred to by their numbers, 2 and 4 respectively.
2) The astrometry has been improved. It is carried out as described in
Pozzo et al (2003) but now entirely with respect to the 2MASS
catalogue. The resulting fits have RMS residuals of about 0.09
arcseconds, which is a significant improvement on the 0.35-0.53 when
we used USNO-A2 reported in
Pozzo et al. Furthermore the systematic
residuals reported in
Pozzo (2001) are no longer
Note that we have not attempted to join the two CCDs into a virtual mosaic.
