\caption{\label{tab6}Mass modelling results for different light profile 
representations. The modelled projected half-light radius $r_{\rm h,p}$, central 
velocity dispersion $\sigma_0$, global velocity dispersion~$\sigma$, mass and 
mass-to-light ratio in the $V$-band are given.
The adopted surface brightness profile parameters are taken from Evstigneeva
et~al. (\cite{evst06}). Radii ($R_{\rm b}$, $R_{\rm e}$, $R_{\rm c}$ and $R_{\rm t}$) are in pc; 
$\mu_{\rm 0,King}$ and $\mu_{e,\rm Sers.}$ are in mag~arcsec$^{-2}$ in the
$V$ band.
In the last rows the results for the virial mass estimator are given. The
effective radius $R_{\rm eff}$ was taken from Table 10 of Evstigneeva et~al. 
(\cite{evst06}), the global velocity dispersion from the generalized King 
models and King + Sersic models in two-component fits case. Also the
ellipticies ($\epsilon = 1-b/a$) from Evstigneeva et~al. are shown for
reference. The values in bold face were adopted for further analyses.}
