The Magellanic Catalogue of Stars (MACS)

Abstract

Abstract. -We have compiled the Magellanic Catalogue of Stars (MACS), a catalogue of positions for 243 561 stars covering large areas around the Large and Small Magellanic Cloud (LMC and SMC). The positions have been measured using ESO Schmidt plates and refer to the FK5 system via the PPM catalogue. A comparison of positions from different plates shows internal errors at a level of 0. 15 to 0. 23. The positional accuracy is estimated to be better than 0. 5 per coordinate for 99% of the stars. The limiting magnitude of the MACS is B ≤ 16. m 3, but the catalogue is not complete: only those stars are included which are undisturbed by close neighbours as verified by visual screening in order to obtain a clean astrometric reference. We introduce for the MACS a nomenclature and numbering system in accord with IAU rules based on position, leaving the possibility to add further stars without upsetting the numbering system. The catalogue is available via the Centre des Données Strasbourg (CDS).

The Magellanic Clouds Photomtric Survey: The Small Magellanic Cloud Stellar Catalog and Extinction Map

“…The astrometric solution is derived from a comparison with stars in the Magellanic Catalogue of Stars (Tucholke, de Boer, & Seitter 1996), whose coordinates are on the FK5 system. Solutions are reviewed and iterated if either the number of stars in the solution is less than 20 over the $12 0 Â 12 0 subscan or the rms positional scatter of the matched stars is larger than 0>5.…”

A photometric and spectroscopic study of the association LH 47 in the superbubble N 44 in the LMC

“…For the R passband we used k R = 0.04 mag, for the I passband we didn't apply an extinction correction. Tucholke et al 1996) are marked on the V exposure The Hα magnitudes have not been calibrated. The images of Oct. 3 then have been calibrated with those of Oct. 4.…”

“…Figure 2 shows two CMDs (V vs. B − V and V vs. U − B) of all stars in the field of view. Table 4, which is also available electronically only, gives all 51 stars which could be cross identified in the MACS (Magellanic Catalogue of Stars; Tucholke et al 1996;de Boer et al 1995). These stars may serve as an astrometric reference grid.…”

The Magellanic Clouds Photometric Survey

“…White circles are areas in which saturated stars have been removed. 321 (Landolt 1992) and astrometry is derived from a comparison to the Magellanic Catalogue of Stars (Tucholke et al 1996).…”
