The ESA Astrophysics Division and the ISOPHOT consortium led by the Max Planck Institut für Astronomie in Heidelberg (MPIA) have developed in a joint effort the ISOPHOT Interactive Analysis (PIA) package. Although this package was initially developed for the processing of the calibration data, the package is available for the general astronomical community. PIA runs under IDL 5.0 and many routines are available for the processing and scientific analysis of ISOPHOT products. For more information we refer to:

To perform all OLP processing as described in this handbook starting from ERD, PIA requires the products IRPH, PSTA, and P*ER where the (*) stands for S, P, 1, or 2 depending on the subsytem used, see e.g. next chapter. Contrary to what is provided by IDA, the input filenames for PIA must be in upper case to conform to the descriptions provided in this document.
