Magellanic Catalog of Stars
Listed in NASA Data Portal
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 Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC).
Description
The positions refer to the FK5 system via the PPM Catalog. A comparison of positions from different plates shows internal errors at a level of 0.15 to o.23 arcseconds; the positional accuracy is estimated to be better than 0.5 arcseconds for 99% of the stars.
The limiting blue magnitude of the MACS is less than 16.5 magnitudes, but the catalog is not complete to this level, as only those stars are included which are undisturbed by close neighbors as verified by visual (interactive) screening (in order to obtain a clean astrometric reference). This database table was created at the HEASARC in June 1998 based on the ADC/<a href="cdsarc.cds.unistra.fr/ftp/cats/I/221">CDS Catalog I/221</a>.
