dpssvali

The task dpssvali performs validation checks of XMM PPS files making it the automatic part of the Data Product Screening System (DPSS). The tests include existence and parameter range checks for header key words and source tables columns of EPIC PPS Fits files. The output of the validation is written to the files 'invalid.log' and 'valid.log'. The checks to be carried out are coded in ascii files, which can be easily modified. Each ascii check file contains a sequence of commands which refer to a certain group of XMM PPS products, e.g. bkgmap.chk for all EPIC background maps. The task dpssvali selects a certain check file for execution in dependence of the PPS product type.
