Abstract:

The ISOPHOT Interactive Analysis PIA, is a calibration, scientific analysis and visualization tool for accessing and processing ISOPHOT data. ISOPHOT is one of the instruments on board the Infrared Space Observatory ISO, launched in November 1995 by the European Space Agency. PIA is an IDL based package, comprising around 1500 routines including a user friendly graphical interface. All the capabilities of input/output, processing and visualization can be reached from window menus, for all the different ISOPHOT sub-systems in all the different levels of data reduction. This applies, starting from digital raw data, coming from the ISO telemetry, to the final level of calibrated images, spectra, multi-filter, multi-aperture photometry. In this article the needs for such a dedicated package are explained, its development and main design features are described, and an overview of the PIA capabilities in the different areas is given.
