In Paper I we showed that multi-phase gaseous halos of late-type spiralgalaxies, detected in the radio continuum, in Halpha, and in X-rays, areremarkably well correlated regarding their morphology and spatial extent. Inthis work we present new results from a statistical analysis in order tospecify and quantify these phenomenological relations. This is accomplished byinvestigating soft X-ray (0.3-2.0keV) luminosities, FIR, radio continuum,Halpha, B-band, and UV luminosities for a sample of 23 edge-on late-type spiralgalaxies. Typical star formation indicators, such as SFRs, are determined and astatistical correlation analysis is carried out. We find strong linearcorrelations, covering at least two orders of magnitude, between star formationindicators and integrated (disk+halo) luminosities in all covered wavebands. Inaddition to the well established L_FIR/L_1.4GHz-relation, we show new andhighly significant linear dependencies between integrated soft X-rayluminosities and FIR, radio continuum, Halpha, B-band, and UV luminosities.Moreover, integrated soft X-ray luminosities correlate well with SFRs and theenergy input into the ISM by SNe. The same holds if these quantities areplotted against soft halo X-ray luminosities. Only a weak correlation existsbetween the dust mass of a galaxy and the corresponding X-ray luminosity. Amongsoft X-ray luminosities, baryonic, and HI-gas masses, no significantcorrelations are found. There seems to exist a critical input energy by SNeinto the ISM or a SFR threshold for multi-phase halos to show up. It is stillnot clear whether this threshold is a physical or an instrument dependentsensitivity limit. These findings strongly support our previous results, butconflict with the concept of halos being due to infalling gas from the IGM.Comment: 8 pages, 3 figures, 1 table, accepted for publication in A&
