flux densities and 8 galaxies with <span style="font-variant:small-caps;">sfind</span> flux densities. For these detections, we add additional 1% calibration error[^4]. For non-detections, we provide 3-$\sigma$ upper limits estimated from the aperture photometry if the aperture is available (37 galaxies). Otherwise we provide 3-$\sigma$ upper limit assuming an underlying point source as a rough estimation (3 galaxies). For sources without LVHIS broad band continuum image (16 galaxies, including NGC 253 and NGC 4945), we use literature flux densities (8 galaxies) close to our frequency ($1.4\,\mathrm{GHz}$) and preferentially from extended photometry. If no error is given in literature, we assume 5% uncertainty. The total detection rate we achieve is 41.5% (34 galaxies). The results are summarized in Table \[tab:flux\], in which the “Flag” column indicates the source of the radio flux density we use.

FIR flux density
----------------

We measure FIR flux densities from IRAS all-sky survey data [@1984ApJ...278L...1N]. The angular resolution of IRAS is poor, 60 and 100 arcsec at 60[$\,\mathrm{\mu m}$]{} and 100[$\,\mathrm{\mu m}$]{} (diameter of 80% encircled energy, diffraction limited). However, some of LVHIS galaxies are still extended. Fluxes from pipeline produced IRAS catalogues, i.e. the Point Source Catalog (PSC) and the Faint Source Catalog (FSC), are expected to be
