Top: Spitzer/IRAC (3.6–4.5, 4.5–5.8) μm diagram of objects in the SINFONI field centered on IRAS 06084-0611. Photospheric colors from main-sequence stars are usually located around (0, 0). The extinction vector has been calculated using the extinction law of Chiar & Tielens (2006). Bottom: Spitzer (3.6–4.5, 5.8–8.0) μm diagram. We used Allen et al. 2004 and Megeath et al. 2004 to specify the location of class 0/I, class I/II and class II sources (dotted lines).
