J/AJ/89/636         Giant M stars in Baade's Window          (Blanco+, 1984)

Giant M stars in Baade's Window. Blanco V.M., Mccarthy M.F., Blanco B.M. <Astron. J., 89, 636-647 (1984)> =1984AJ.....89..636B
ADC_Keywords: Stars, giant ; Stars, M-type ; Photometry Abstract: Near-infrared small-dispersion spectra obtained with a grism at the prime focus of CTIO's 4-m telescope have been used to survey and classify late-type red giants found in a circular area with a diameter of 24.4 arcmin which is contained within Baade's Window. The survey is complete to a distance that extends past the galactic nuclear bulge. The presented stars therefore constitute a unique complete sample of the red giant population of the nuclear bulge. A total of 306 red giants, including all giants of type M6 or later, are presented with a list of their coordinates, spectral classes, and apparent I magnitudes. A finding chart is also given. No C or S stars were found even though they should have been detected if they exist. Evidence is presented of uneven foreground interstellar obscuration in Baade's Window. Description: The list below provides improved coordinates and a few IDs for the 306 late-M giants near NGC 6522 reported by Blanco et al. I used the source coordinates as a start, and matched against the 2MASS catalogue. The positions are systematically off by 2"-4", with many in error by ∼10"; a few are simply wrong by larger amounts. The chart provided with the paper was indispensable in identifying the stars, which I did using cut-outs mostly from 2MASS J-band images, which matched the I-band chart photo fairly well. The remarks indicate when there is a large error of some sort, sometimes a typo and others an outright error. The Blanco spectral types and 'I' mags are copied. I matched the corrected coordinates against MSX6C and GCVS v4.1, accepting only quite close matches (generally < 4"). There are many additional GCVS/NSV names that are "likely" matches, but since work on this area by the GCVS group is not yet published, I defer going further with the IDs. Likewise I have ommitted matching against OGLE and various near-IR surveys - coordinates need to be checked for systematic differences for many of these. File Summary:
