Description

The SAS task dpssvali is part of the Data Product Screening System (DPSS), which is divided into an automatic step (described here) and an subsequent visual verification step based on Graphical User Interfaces. The separation into an automatic validation and a visual verification process has been proven as an effective and powerful method to secure a high quality of data products produced by a standard analysis software. The SAS task dpssvali is written in perl and depends on the SAS task dscheck. For a certain group of XMM PPS products (e.g. EPIC background maps, EPIC maximum-likelihood source lists, EPIC images, EPIC sensitivity maps) a list of commands is executed stored in an ascii file (hereafter check file). 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. 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 are coded in ascii files, which can be easily modified.

The following ascii check files are presently available:
