\tablefoot {$\LX$ is the $[0.1{-}2.4]~\keV$ luminosity  within $\Rv$. MB: relations corrected for Malmquist bias. For each observable set,~$(B,A)$, we fitted a power law relation of the form $B  = C(A/A_0)^\alpha$, with $A_0 = 10^{44}~{h_{70}^{-2}}$~ergs/s and $3$~$\times$ $10^{14}~{h_{70}^{-1}}~\msol$ for $\LX$ and~$\Mv$, respectively.   $\sigma_{\rm log,i}$:~intrinsic scatter about  the best fitting relation in the $\log {-} \log$~plane.}
