The ISOPHOT 170 μm serendipity survey -: II.: The catalog of optically identified galaxies

The ISOPHOT Serendipity Sky Survey strip-scanning measurements covering approximate to15% of the far-infrared (FIR) sky at 170 mum were searched for compact sources associated with optically identified galaxies. Compact Serendipity Survey sources with a high signal-to-noise ratio in at least two ISOPHOT C200 detector pixels were selected that have a positional association with a galaxy identification in the NED and/or Simbad databases and a galaxy counterpart visible on the Digitized Sky Survey plates. A catalog with 170 mum fluxes for more than 1900 galaxies has been established, 200 of which were measured several times. The faintest 170 mum fluxes reach values just below 0.5 Jy, while the brightest, already somewhat extended galaxies have fluxes up to approximate to600 Jy. For the vast majority of listed galaxies, the 170 mum fluxes were measured for the first time. While most of the galaxies are spirals, about 70 of the sources are classified as ellipticals or lenticulars. This is the only currently available large-scale galaxy catalog containing a sufficient number of sources with 170 mum fluxes to allow further statistical studies of various FIR properties.
