The ISOPHOT Interactive Analysis (PIA), originally conceived as a tool for ISOPHOT data processing to be used by calibration experts, rapidly became the software of choice for scientific data reduction of ISOPHOT observations. In this paper we summarize the enhancements of PIA in the last year, and discuss in particular its capabilities for

The European Large Area ISO Survey (ELAIS) has surveyed ~ 12 square degrees of the sky at 15 and 90 μ m and subsets of this area at 6.75 and 175 μ m using the Infrared Space Observatory (ISO). This project was the largest single open time programme executed by ISO, taking 375 hours of data. A preliminary catalogue of more than 1000 galaxies has

We have studied the physical conditions in the central 300 pc of the prototypical starburst galaxy NGC 7714. Our analysis is based on ultraviolet spectroscopy with the HST/GHRS and ground-based optical observations, and it also covers X-ray and radio data taken from the literature. The data are interpreted using evolutionary models optimized for

We present Hα, [N II] lambda6583, [O III] lambda5007 ground-based images, Hubble Space Telescope (HST) (V band) archival images, VLA-A 3.6 cm continuum data, and high-resolution long-slit spectra of the planetary nebula NGC 6884. The VLA and HST images show an extremely knotty and filamentary nebula with an elliptical central structure also
