Fig. 12
Selected YSOs in our VISTA Orion A survey. Class I and Class II sources were taken from Megeath et al. (2012), Class III objects from Pillitteri et al. (2013). Class III sources are virtually indistinguishable from more evolved stars in NIR colors, while Class I and Class II sources very often show characteristic structures of scattered light. The labels in the bottom left corners refer to Table B.2.
