The Infrared Space Observatory ISO, launched by ESA in November 1995, ended its operations succesfully in April 1998. The subsequent post-operational phase, which will last for 3,5 years, is devoted mainly to re-analysis and re-calibration of the data. The ESA ISO Data Centre at Villafranca, Spain, as the central place for maximising exploitation of the ISO data in a net of data centres in Europe and the USA, is also in charge of the further development and maintenance of the ISOPHOT Interactive Analysis (PIA). PIA is not only the main calibration tool but also the software tool of choice for the scientific analysis of data obtained with the imaging photo-polarimeter ISOPHOT. The main PIA enhancements during the last year as well as plans for the near future will be presented in this paper.
