Abstract
The ISOPHOT Serendipity Sky Survey strip-scanning measurements covering $\approx$ $15\%$ of the far-infrared (FIR) sky at ${\rm 170\,\mu m}$ 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 ${\rm 170\,\mu m}$ fluxes for more than 1900 galaxies has been established, 200 of which were measured several times. The faintest ${\rm 170\,\mu m}$ fluxes reach values just below 0.5 Jy, while the brightest, already somewhat extended galaxies have fluxes up to $\approx$600 Jy. For the vast majority of listed galaxies, the ${\rm 170\,\mu m}$ 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 ${\rm 170\,\mu m}$ fluxes to allow further statistical studies of various FIR properties.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
