Beginning of ReadMe : J/ApJS/209/27 MYStIX: the Chandra X-ray sources (Kuhn+, 2013) ================================================================================ The Massive Young star-forming complex Study in Infrared and X-ray: X-ray sources in 10 star-forming regions. Kuhn M.A., Getman K.V., Broos P.S., Townsley L.K., Feigelson E.D. <Astrophys. J. Suppl. Ser., 209, 27 (2013)> =2013ApJS..209...27K ================================================================================ ADC_Keywords: X-ray sources ; H II regions Keywords: H II regions - stars: activity - stars: formation - stars: pre-main sequence - X-rays: stars Abstract: The Massive Young star-forming complex Study in Infrared and X-ray (MYStIX) uses data from the Chandra X-Ray Observatory to identify and characterize the young stellar populations in 20 Galactic (d<4kpc) massive star-forming regions. Here, the X-ray analysis for Chandra ACIS-I observations of 10 of the MYStIX fields is described, and a catalog of >10000 X-ray sources is presented. In comparison to other published Chandra source lists for the same regions, the number of MYStIX-detected faint X-ray sources in a region is often doubled. While the higher catalog sensitivity increases the chance of false detections, it also increases the number of matches to infrared stars. X-ray emitting contaminants include foreground stars, background stars, and extragalactic sources. The X-ray properties of sources in these classes are discussed. Description: X-ray observations were made with the imaging array on the Advanced CCD Imaging Spectrometer (ACIS-I) on board the Chandra X-Ray Observatory. This array of four CCD detectors subtends 17'x17' on the sky. Data were acquired from the Chandra Data Archive from 2001 Jan to Mar 2008 for 10 MYStIX fields (Flame Nebula, RCW 36, NGC 2264, Rosette Nebula, Lagoon Nebula, NGC 2362, DR 21, RCW 38, Trifid Nebula and NGC 1893); see table1.
