Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

Abstract:
We present photometry and a preliminary interpretation of a UBVR
survey of the Large and Small Magellanic Clouds, which covers 14.5
deg2 and 7.2deg2, respectively. This study is aimed at obtaining
well-calibrated data on the brighter, massive stars, complementing
recent, deeper CCD surveys. Our catalog contains 179,655 LMC and
84,995 SMC stars brighter than V~18.0, and is photometrically complete
to U~B~V~15.7 and R~15.2, although stars in crowded regions are
selectively missed. We compare our photometry to that of others, and
describe the need for gravity-dependent corrections to our CCD U-band
photometry. We provide a preliminary cross-reference between our
catalog stars and the stars with existing spectroscopy.

suggest foreground stars.
