Observations of OMC 2/3. Left: column densities from Stutz & Kainulainen (2015) at ~36′′ resolution and assuming a fixed dust opacity law. The complexes are separated by dashed lines based on Chini et al. (1997). The H ii region, M 43, is also labeled. Right: IRAM 2 mm observations at 21′′ resolution. Contours show 2 mm flux density levels of 0.02, 0.08, 0.3, and 1 Jy beam-1. Respective beams are shown in the the lower left corners.
