Post Search Processing

Both PSS and EVPSS share the same output format. The prerequisites of such a format are that its structure be sufficiently rich to represent the information which are required to be stored, and that it is easy to export the data to other formats or feed it into other applications. The ASTERIX source search dataset (SSDS) is an HDS file format which permits storage of,

• Bookkeeping information about the parameters used in the various preceding applications used to create the dataset.
• Field information about each source. Consists of the data value or values, errors both symmetric and asymmetric, at multiple levels of confidence, along with units information and other ancillary information. Although certain field names are reserved, extra fields can be written by new applications such as exposure correction program and database software.
• Bulk data relating to the whole dataset, eg. sensitivity maps.

ASTERIX applications exist to print ascii reports of SSDS, export to common database formats and manipulate results graphically.
