| Popis: | Aims. We describe the mid- (MIR) and far- (FIR) infrared properties of a large (-1000) sample of the most isolated galaxies in the local Universe. This sample is intended as a "nurture-free'' zero point against which more environmentally influenced samples can be compared. Methods. We reprocess IRAS MIR/FIR survey data using the ADDSCAN/SCANPI utility for 1030 out of 1050 galaxies from the Catalogue of Isolated Galaxies (CIG) as part of the AMIGA project. We focus on diagnostics (FIR luminosity $L_{\rm FIR}$, $R=\log(L_{\rm FIR}/L_{B})$, and IRAS colours) thought to be sensitive to effects of environment or interaction. Results. The distribution of $\log(L_{\rm FIR})$ sharply peaks from 9.0-10.5, with very few ( Conclusions. The results indicate that the FIR emission is a variable enhanced by interaction, and that our sample probably shows the lowest possible mean value. This attests to the utility of our sample for defining a nurture-free zero point. This work has been partially supported by DGI Grant AYA 2005-07516-C02-01 and the Junta de Andalucía (Spain).
