Description
Emission from several metastable states of NH3 is mapped in the OMC-1 and OMC-2 regions. Rotational temperatures are deduced from a comparison of the (J,K) = (1,1), (2,2), and (3,3) lines. A hot core is found at KL, embedded in the cooler OMC-1 ridge. Clumping is found to be extended over the entire OMC-1 region with only about one-tenth of the 1'.4 beam filled by regions which provide most of the emission
