Table 6: Derived physical parameters. Uncertainties on MV are mainly due to the uncertainties on AB. Photometric mass estimates are given for a Kroupa MF and for Salpeter MF with lower mass limit of  $0.1~\mbox{$M_{\odot}$ }$. Central V-band surface brightnesses ($\mu _{0,V}$) in mag arcsec-2 and estimated core densities ($\rho _0$) in $M_{\odot }$ pc-3 are also listed.
