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.

Description:
The Magellanic Catalogue of Stars (MACS) is based on scans of ESO
Schmidt plates and contains about 244,000 stars covering large areas
around the LMC and the SMC. The limiting magnitude is B<16.5m and the
positional accuracy is better than 0.5" for 99% of the stars. The
stars of this catalogue were screened interactively to ascertain that
they are undisturbed by close neighbours.
