(2) Photon index of the power-law. (3), (4) Luminosities of the thermal and power-law components in the $0.5{-}8$~keV energy range. (5) The combined luminosity of unresolved low-mass \mbox{X-ray} binaries brighter than $10^{35} \ {\rm erg \ s^{-1}}$ (but fainter than the sensitivity limit for the given galaxy) estimated from the $K$-band luminosity of the studied region and the average LMXB \mbox{X-ray} luminosity function of \citet{gilfanov}. (6) The observed luminosity ratio of the soft thermal component to the power-law. (7) Same as (6) but corrected for contribution of unresolved LMXBs. For NGC~3377 and NGC~3585, the predicted LMXB luminosity exceeds the observed luminosity of the power-law component, presumably because of a scatter in $X{/}K$ ratios for LMXBs, therefore no LMXB-corrected luminosity ratio is computed.
