THE RADIO-FAR-INFRARED RELATION OF INTERACTING AND NONINTERACTING SPIRAL GALAXIES .1. OBSERVATIONS AND DATA-COLLECTION

We present lambda-6.3 cm radio continuum, HI and far-infrared (FIR) data for a sample of isolated pairs of spiral galaxies, and for a comparison sample of non-interacting ones. Utilizing the HI data we are able to separate the FIR emission of the cold and warm dust component, employing a modification of the model presented by Buat and Deharveng (1988). The FIR flux of the warm dust component is used to estimate the thermal radio emission for some galaxies. A comparison between the calculated thermal lambda-6.3 cm flux densities and those derived from radio observations show a very good agreement. We conclude that the model for the separation of the cold and warm dust component can be used for a further examination of the radio-FIR correlation.
