There is no longer a need to correct the astrometry in Chandra data taken from the CXC
archive, with the possible exception of the following obsids:
12,
82,
400,
526,
and 1456. These obsids (mostly from 1999) all have known issues that prevent normal
reprocessing.
If you are analyzing one of the listed observations and require high-precision astrometry then please contact the CXC help desk. |
