Fig. 6


The L1630 N K-band luminosity function (KLF) before (empty histogram) and after correction for interstellar extinction (line-filled histogram). The labels in the top x-axis indicate the corresponding stellar mass according to the VISTA 2 Myr isochrone (Appendix A). The continuous and dashed vertical lines indicate the completeness and the saturation limit of the VISTA K-band photometry, respectively. The continuous curve is the KLF of the Trapezium cluster (Muench et al. 2002), scaled to the peak of the L1630 N KLF.
