Analysis and calibration tools for both SWAP and LYRA data are distributed in the PROBA2 subtree of the SolarSoft (SSW) packages for IDL. If you have SSW installed on your system already, it is straightforward to add the SWAP and LYRA packages to your installation using the following commands at the IDL prompt in an SSW session. (Note that in order to use the SWAP or LYRA tools, you also need to add each instruement to your instrument list.)
One of the most powerful tools for SWAP is the so-called SWAP Object, which was developed for the SWAP team by the scientists at Trinity College in Dublin. A full tutorial for the SWAP Object and a more general discussion on the TCD objects are available online. The SWAP Object tutorial is also included in SWAP's SSW distribution packages.
Additional information on how to use these tools is included in the software itself. Use the following command at the IDL prompt to view the complete documentation for SWAP software.
