Fig. D1. Spectral Energy Distribution of optical/IR counterparts without IR classification. B and R data come from the PMM USNO-A1.0 catalogue (Monet et al. 1996); J, H, K data come from BKLT; LW2 and LW3 are the ISOCAM upper limit at 10 mJy from Bontemps et al. (2000). The dashed line shows the limit between Class II source and Class III source classification (=dlog()/dlog=-1.5 from GWAYL). "out" means that the source is outside the ISOCAM survey.
