1991A&AS...87..247W The radio-far-infrared relation of interacting and non-interacting spiral galaxies. I.Observations and data collection E. Wunderlich and U. Klein Max-Planck-Institut fur Kernphysik, Saupfercheckweg 1, D-6900 Heidelberg 1, F.R.G. Max-Planck-Institut filr Radioastronomie, Auf dem Hugel 69, D-5300 Bonn 1, F.R.G. Received May 22; accepted August 21, 1990 Abstract. - We present {lambda}6.3 cm radio continuum, H I 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 >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. Key words: galaxIes - radio continuum - far-infrared - neutral hydrogen.
