Notes. COBE [C II] map shows two distinguish source of emissions which are Orion and λ Ori. The rest is emission not connected with these two features called diffuse emission. The Orion complex modeled flux rises from H II region and dense PDR of M 42, M 43, IC343, NGC 2023, NGC 2024, the surface of molecular clouds OMC A and OMC B. The λ Ori complex consists of the molecular rings and ionized gas. The modeled diffuse [C II] consists of CNM, ELDWIM, and Barnard’s Loop. (a) Percentage of observed [C II] flux with respect to the total observed [C II] flux. (b) Percentage of modeled [C II] flux with respect to the total observed [C II] flux. (c) Modeled [C II] emission per selected region relative to the observed [C II] per selected region.
