A patch to the newly released SAS 11.0.0 version has to be issued, due 
to following reasons:


 inconsistencies found in the use of image masks by some of the ESAS tasks 
and the upgraded task emask,

 due to a mistake the documentation of several tasks had not been included in the SAS 11.0.0
release.
 
Some other improvements to ESAS have been added, which need of an upgrade of 
the ESAS CALDB. So, with this patch a synchronization with ESAS CALDB
(ftp://xmm.esac.esa.int/pub/ccf/constituents/extras/esas_caldb) is necessary.
