Details on Acronym:   CXOPS
   CXOPS (Chandra X-ray Observatory Plane Survey) Write:<<CXOPS JHHMMSS.s+DDMMSS>> N: about 10000 Object:(X)  (SIMBAD class: X = X-ray source) Note:Catalog of X-ray sources in the ChaMPlane multiwavelength survey.
2005ApJ...635..907H, 2006ApJS..163..160R: 2 first refs with CXOPS and ChOPS objects. Notes:ChaMPlane is a multiwavelength survey.
This catalog (CXOPS) of X-ray sources will be joined by an optical catalog ChOPS. The two catalogs reference each other to provide X-ray and optical data, flux ratios etc for sources detected in both our Chandra and NOAO surveys.
Infrared data will also be obtained and will follow the same convention, a separate IR catalog ChIPS with cross-referencing to the 2 others. Notes:The Chandra Multiwavelength Plane (ChaMPlane) Survey of the galactic plane incorporates serendipitous sources from selected Chandra pointings in or near the galactic plane (b < 12deg, >20 ksec, lack of bright diffuse or point sources) to measure or constrain the luminosity function of low-luminosity accretion sources in the Galaxy.
The primary goal is to detect and identify accreting white dwarfs (cataclysmic variables, with space density still uncertain by a factor of >10-100), neutron stars and black holes (quiescent low mass X-ray binaries) to constrain their space densities and thus origin and evolution.
Secondary objectives are to identify Be stars in high mass X-ray binaries and constrain their space densities, and to survey the H-R diagram for stellar coronal sources. A parallel optical imaging under the NOAO Long Term Survey program provides deep optical images using the Mosaic imager on the CTIO and KPNO 4-m telescopes.
The 36x36arcmin optical images (Halpha, R, V and I) cover 5X the area of each enclosed Chandra ACIS FOV, providing an extended survey of emission line objects for comparison with Chandra.
Spectroscopic followup of optical counterparts is then conducted, thus far with WIYN and Magellan. This catalog contains all ChaMPlane X-ray sources, their positions, properties and links to probable counterparts in our optical catalog.
