OMC 2
OMC-2 is a region below to OMC-3, which coincides with the Integral Shaped Filament in Orion A Molecular Cloud.
The sources named "HOPS" are the ones detected in the Herschel Orion Protostar Survey (Furlan et al. 2016), while the ones named "Source" were observed later on with VLA (Osorio et al. 2017, Díaz-Rodríguez et al. 2022).
Some VLA sources match HOPS sources and others were new findings in this Orion region.
