    \caption{\label{tab:ld}UV luminosity density ${\cal L}_{1700}(M<-18.5)$ integrated up to $M_{1700}=-18.5$ and total ${\cal L}_{1700}^{{\rm Total}}$ estimated from the VVDS for different fixed values of $\alpha$. "EW'' indicates the equal-weight LFs and "PR'' the photometric-rejection ones. The 68\% and 90\% (in parenthesis) confidence levels are also provided. Units are $10^{18}$~W~Mpc$^{-3}$.}
