Title: The far-infrared properties of the most isolated galaxies

Abstract: Although it is widely accepted that galaxy interactions stimulate secular evolutionary effects (e.g. enhanced star formation) the amplitude of this effect and the processes for accomplishing them, are not well quantified. The goal of the project AMIGA (Analysis of the Interstellar Medium of Isolated Galaxies) is to provide a sizable reference sample (n=1050) of the most isolated galaxies as a basis for the study of the influence of the environment on galaxy properties. Here, we present the far-infrared (FIR) properties of 1030 galaxies of the sample for which IRAS data are available. We improved the detection rate and accuracy of the IRAS data with respect to the Point Source and Faint Source Catalog by redoing the data reduction with the IPAC utility ADDSCAN/SCANPI. Comparing the FIR to the blue luminosities, we find a slightly non-linear relation. Furthermore, we find that interacting galaxies tend to have an enhanced FIR emission.
