Description:
The Far Infrared (FIR) properties of galaxies which are members of
compact groups bear relevant information on the dynamical status and
the physical properties of these structures. All studies published so
far have been undermined by the poor sensitivity and spatial
resolution of the IRAS-PSC and IRAS Sky Survey data. We used the HIRAS
software available at the IRAS server at the Laboratory for Space
Research in Groningen to fully exploit the redundancy of the IRAS data
and to approach the theoretical diffraction limit of IRAS. Among the
97 groups which were observed by IRAS, 62 were detected in at least
one band, while reliable upper limits were derived for all the others.
Among the detected groups, 49 were fully or partially resolved, i.e.
it was possible to discriminate which member or members emit most of
the FIR light. At 60µm, for instance, 87 individual sources were
detected in 62 groups. In order to ease the comparison with data
obtained at other wavelengths - and in particular in the X and radio
domains - we give co-added and HIRAS maps for all the detected groups.

Note (1): If the group is not detected in any of the IRAS bands there is only
one entry
Note (2): When the FIR source corresponds to several unresolved members of the
group, we give (in brackets) the list of the members which fall
within the FIR source
