ISOGAL Survey

The ISOGAL survey is one of the largest imaging programme performed by the ISO satellite. About 16 sq. deg. mainly distributed in the inner Galactic disk were mapped at 7 and/or 15 micron. Because of highly structured background and high source density, a special point source extraction algorithm was used and resulted in a 100,000 point source catalogue. The mid-infrared data have been associated with near-infrared DENIS sources, providing an up to five wavelength photometric catalogue with a typical astrometric accuracy better than 1 arcsecond. The point source catalogue contains the positional and photometric parameters of all ISOGAL sources, together with various quality flags aimed at giving an estimate of the reliability of the detections and of the associations between the different bands.
