-{{{ippToPsps}}} is the interface between IPP and PSPS. It generates FITS files from IPP data that are suitable for consumption into the PSPS database. In short, {{{ippToPsps}}} creates FITS files from data found in IPP {{{smf}}} and {{{cmf}}} files, as well as relevant DVO databases, then publishes them to a datastore in the form of ''jobs''. On the PSPS side, the DXLayer polls the datastore, collects jobs when they become available, converts the contents to {{csv}} files then sends them on to special MSSQL loader software, which inserts them into the PSPS database. Ultimately there will be feedback from PSPS regarding errors in the received data, to which {{{ippToPsps}}} will need to respond.

-It is intended that the binary tables in the FITS files generated by {{{ippToPsps}}} match the PSPS database schemas perfectly, the consequence being that any alterations to the PSPS database schema will require changes to {{{ippToPsps}}} code.

+{{ippToPsps}} is a C program within the IPP build. When given the correct arguments it will generate a single FITS for the specified product (above). The program is run from a perl script, which itself is provided ... in order to generate the arguments necessary to run {{ippToPsps}}.
