S2 Catalogues

The S2 format catalogue is a binary file containing data about sources found in the S2 pipeline processing. It is accompanied by a description file which enables it to be read by SCAR, the StarLink Catalogue Access and Reporting System.

However, for reasons of efficiency, much of the data is compressed and is not immediately understandable using the SCAR reporting program, CAR_REPORT. For reporting purposes the S2CATLIST application should be used.

In all other respects S2 catalogues can be manipulated by SCAR commands.
