Abstract

The Long Wavelength Spectrometer was one of two complementary spectrometers on the Infrared Space Observatory (ISO). The LWS operated between 44 and 197 microns either in medium resolution mode, using a diffraction grating, or in high resolution mode where a Fabry Perot was also placed in the beam. All LWS data is processed through a standard 'pipeline' and this standard processing is adequate for the majority of the data. However, as the understanding of instrument behaviour increased during operations, it became apparent that various modes, in particular the Fabry Perot scanning mode, could be better processed in an interactive manner. A complementary LWS Interactive Analysis (LIA) system was then developed for the scientific part of the data processing. The LIA system allows users to access the processing steps, in terms of visualisation of intermediate products and for interactive manipulation of the data at each stage. This paper describes the LIA system and details in terms of instrument behaviour those data sets that require interactive processing. Following the release of the ISO Legacy Archive in 2001, LIA 10 was released in November 2001. A further update, LIA 10.1, will be released later this year and we outline the new features along with some of the most commonly used LIA routines.
