Figure 4: Effect of NIR photometry in the mass determination: ratio between masses estimated without and with NIR photometry vs. mass determined without NIR photometry. The data have been split into different redshift ranges. Left: masses determined using smooth SFHs. Right: the same, but using complex SFHs. |

Figure 5: Histograms of the ratio of the masses derived with the smooth and the complex star formation histories. In the upper panel (z<1.2) both data from the I-selected and the K-selected samples are shown; in the lower panel (z>1.2) only data from the K-selected sample are shown, since the I-selected sample is not used to derive the mass function in this redshift range. |

Figure 7: Effect on the I-selected MF of the use of the statistically corrected masses, which take into account the effect of near-IR photometry on the mass determination (see text for details). Complex SFHs have been used to derive masses. Empty circles represent the MF obtained using the original uncorrected masses, filled squares show the MF obtained using the statistically corrected masses. For comparison the STY Schechter MF is shown for the subsample where near-IR photometry is available. The vertical dashed lines represent the completeness limit of the sample as defined in the text. |

Figure 8: K-selected MF derived from the 2 subsamples, deep (filled circles) and shallow (empty circles), separately (smooth SFHs have been used to derive masses). For comparison the STY Schechter MF for the global K-selected sample is shown. The vertical dashed lines represent the completeness limit of the 2 K-selected subsamples. |

Figure 9: Galaxy stellar mass functions in the I-selected (squares) and K-selected (triangles) using both methods to estimate the stellar masses (empty symbols for smooth SFHs and filled for complex SFHs). The STY Schechter fits for the 2 methods limit the hatched regions (horizontal hatched for the K-selected and vertical hatched for the I-selected samples). Vertical hatched regions represents the completeness limit of the 2 samples. The local MFs by Cole et al. (2001), both original and "rescaled'' version (Fontana et al. 2004), and by Bell et al. (2003) are reported in each panel as dotted lines. |

Figure 10: Comparison between the I-selected and the K-selected MFs in the VVDS (hatched vertical and horizontal STY regions, respectively, see caption Fig. 9) and the literature data (K20, COMBO17, MUSIC, DEEP2, FDF+CDFS; for each the band of selection is indicated in the parenthesis). The vertical hatched regions represent the completeness limits of the VVDS samples. |
