XMM-Newton Science Analysis System
catcorr (catcorr-0.7) [xmmsas_20121219_1645-12.0.1]
Catcorr updates the positions of sources in an EPIC source list in an OBSMLI file.
It derives these by cross-matching the positions with up to
three reference catalogues to find optical or
infra-red counterparts and finding the small frame shifts or rotations which
optimise the match. These are then applied to all the detected positions.
It is designed as a replacement for eposcorr and evalcorr.
