Table 2: Sample of protostars surveyed in Ophiuchus. ISO numbers, infrared spectral indices and bolometric luminosities are from Bontemps et al. (2001), while the near-infrared magnitudes are from Barsony et al. (1997), Greene et al. (1994) and the 2MASS database (2MASS uses a $K{\rm s}$ filter rather than a K filter; the difference in magnitude for an object can reach a few tenths of a magnitude). The source marked with a $\dagger $ symbol has an infrared spectral index typical of a normal Class II source but Ressler & Barsony (2001) have shown that this system contains a Class I source and it is classified as such here. The last three columns have the same meaning as in Table 1. The existence of an envelope is taken either from André & Montmerle (1994) and Motte et al. (1998) or from our reexamination of the mosaic presented in the latter. (Note that this classification is more uncertain than in Taurus due to the smaller size of protostellar envelopes in Ophiuchus. Particularly uncertain cases are flagged with a "?''.)
