Table 3: Slope $\alpha$ of the luminosity functions for the different wavebands as determined from an error-weighted fit to the data in Table 2 under the assumption that $\alpha (z)={\rm const.}$ (upper part). In the lower part of the table we show the best values of $\alpha$ after combining the UV bands and the blue optical bands.
Filter $\alpha (z)={\rm const.}$
