J/A+A/462/507 AMIGA III. IRAS data (Lisenfeld+, 2007) ================================================================================ The AMIGA sample of isolated galaxies. III. IRAS data and infrared diagnostics. Lisenfeld U., Verdes-Montenegro L., Sulentic J., Leon S., Espada D., Bergond G., Garcia E., Sabater J., Santander-Vela J.D., Verley S. =2007A&A...462..507L ================================================================================ ADC_Keywords: Galaxies, optical ; Infrared sources Keywords: galaxies: evolution - galaxies: interactions - galaxies: luminosity function, mass function - surveys - infrared: galaxies Abstract: 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. 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, Cat. ) as part of the AMIGA survey. We focus on diagnostics (FIR luminosity LFIR , R=log(LFIR/LB) and IRAS colours) thought to be sensitive to effects of environment or interaction. Description: The AMIGA project aims at Analysing the interstellar Medium of Isolated Galaxies. File "table2.dat" contains the CIG number, FIR flux densities at 12, 25, 60 and 100um for the CIG galaxies, together with estimation methods and whether the value is an upper limit or not. File "table3.dat" contains the CIG number, distance (in Mpc), and log(LFIR) and log(LB) as a fraction of solar luminosity.

The bivariate (optical, FIR) luminosity function {Theta}(L/Mj) is defined as Theta(L/Mj)=[P(L,Mj)]/{Delta}L, where {Delta}L=0.25 and P(L,Mj) is the conditional probability for a source with absolute magnitude M (Mj+0.5{Delta}M>=M>=Mj-0.5{Delta}M) to have the logarithm of its FIR luminosity, log(L_FIR_), within the interval [L-0.5{Delta}L,L+0.5{Delta}L]. Note (2): LFIR luminosity is an upper limit when l_logLFIR="<", else LFIR luminosity has been measured. Note (3): Logarithm of galaxy luminosity over solar luminosity.
