Abstract:
The Master Catalogue of stars towards the Magellanic Clouds (MC2) is
a multi-wavelength reference catalogue. The current paper presents
the first results of the MC2 project. We started with a massive
cross-identification of the two recently released near-infrared
surveys: the DENIS Catalogue towards the Magellanic Clouds (DCMC) with
more than 1.3 million sources identified in at least two of the three
DENIS filters (I J Ks) and the 2nd Incremental Release of the 2MASS
point source catalogue (J H Ks) covering the same region of the sky.
Both point source catalogues provide an unprecedented wealth of data
on the stellar populations of the Magellanic Clouds (MCs). The
cross-matching procedure has been extended to optical wavelength
ranges, including the UCAC1 (USNO) and GSC2.2 catalogues. New
cross-matching procedures for very large catalogues have been
developed and important results on the astrometric and photometric
accuracy of the cross-identified catalogues were derived. The
cross-matching of large surveys is an essential tool to improve our
understanding of their specific contents. This study has been partly
supported by the ASTROVIRTEL project that aims at improving access to
astronomical archives as virtual telescopes. This work has been
supported by ASTROVIRTEL, a project funded by the European Commission
under FP5 Contract No. HPRI-CT-1999-00081.
