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 60{mu}m, 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
