   CXOM31 (Chandra X-ray Observatory, M 31) Write:<<CXOM31 JHHMMSS.s+DDMMSS>> Object:(X)  (SIMBAD class: X = X-ray source) Note:Chandra X-ray sources in the central region of M 31.
See also [KGP2002].
There are many Chandra observing programs on M31.
One is a 'monitoring' program surveying M31 about one month.
There are several other deeper, but smaller FOV programs targeting specific sections of the galaxy.
