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.
