Decimal logarithm of the luminosity in the K-band in units of the solar luminosity in the KS-band (LK,⊙ =5.0735 × 1032 erg s−1).
Decimal logarithm of the luminosity at 24 μm, derived fromSpitzer MIPS fluxes as L24 μm = νf24 μm × 4πD2. The fluxes were obtained from Engelbracht et al. (2008, II Zw 40, NGC 1569, NGC 2146, NGC 3310, NGC 4449, NGC 3079), Dale et al. (2009, NGC 3034, NGC 4490, NGC 4631, NGC 5194), Brown et al. (2014, NGC 6052), or directly from the Spitzer archive (https://irsa.ipac.caltech.edu) (II Zw 70). For two galaxies (IC 10 and NGC 4038), no Spitzer MIPS data were available and we used IRAS 25 μm instead, neglecting the slight difference in the central wavelength.
Decimal logarithm of the Hα flux, corrected for N ii contribution and for Galactic foreground extinction.

Decimal logarithm of the SFR, calculated with Eq. (2).
