Description

The SAS task dpsssrc is part of the Data Product Screening System (DPSS), which is divided into an automatic step (described here) and a 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 dpsssrc is designed to speed up the work of the visual verification step by creating a copy of the EPIC Maximum-Likelihood source list containing three new column necessary for the work with the DPSS GUI. The columns created by the task are named as: (i) IND_SOL, (ii) VER_FLAG and (iii) VER_COMM. The column IND_SOL (data format: 4-byte INTEGER) is filled with a running number, starting from 1 to the number of rows in the source table. The column VER_FLAG (data format: A10) contains the source flag setting (the preflag setting is: FFFFFFFFFF, i.e. none of the source flags is given to a source). In addition the columns A, E, N, P, G and X are created containing the flag setting of individual source flags. The column VER_COMM (data format: A20) is created to be filled with source comments during the visual verification step. The source flag source likelihood below a certain threshold (position 2 of the column VER_FLAG) is set to T, when the source likelihood listed in the column DET_ML is below a certain threshold.
