Release of the Observers SWS Interactive Analysis Package The Observers SWS Interactive Analysis Package (OSIA) has been released! This package, complementary to the ISO Spectral Analysis Package (ISAP), may be used to reduce SWS data from the ERD to the AAR level. It is a public version of the SWS Interactive Analysis system used at the Vilspa ground station and various SWS institutes in the calibration of the SWS instrument and was produced by the Space Research Organisation Netherlands (SRON), Katholieke Universiteit Leuven (Belgium), MPE Garching and the European Space Agency. OSIA has tools to allow you to e.g. reprocess ERD and SPD either automatically or fully interactively, remove fringes, look at your data via plotting, listing or checking status/flag words, rebinning and combining. All tools come with an extensive set of documentation. The homepage for OSIA can be found at http://sws.ster.kuleuven.ac.be/osia/ This pages includes documentation and allows users to enter Software Problem Reports (although users are encouraged to check the current list before entering a new SPR). OSIA may be downloaded from this site by following the 'Download' link and filling the form with the requested information. Your name and email address will never be distributed outside the SWS consortium and will only be used for statistical purposes (i.e. usage of OSIA). OSIA has been tested on Unix and Vax machines and requires IDL.
