Several interactive analysis packages, written in IDL, are available at the UK LWS web site:

LWS parallel mode products and analysis tools
to analyse the products of parallel and serendipity observations. They can either be run interactively from the command line or via a GUI. These allow combining individual rasters and pointings into uniformly gridded maps. There are also routines which allow potential point sources to be extracted from serendipity mode and maps to be produced from serendipity mode observations. Further analysis can then be done on the maps with other packages.
