Notes. (a) Scaling flux is the flux used to scale the modeled [C II] emission from MAPPINGS (in unit of erg s−1 cm−2). (b) Solid angle occupied by the components in steradian. (c)The observed surface brightness quoted is from Stacey et al. (1993); Pabst et al. (2019) observation. These observations coincide with region I with modeled [C II] surface brightness is ~2.2 × 10−4 erg s−1 cm−2 sr−1. Stacey et al. (1993); Pabst et al. (2019) have smaller surface area hence we do not compare flux. (see Sect. 3.4 for detailed explanation). The modeled surface brightness are listed in Table 4. (d) The observed surface brightness is from Goldsmith et al. (2016). The observation point coincides with region 13 of λ Ori Molecular clouds. Goldsmith et al. (2016) observed smaller surface area hence we do not compare flux. (see Sect. 3.4 for detailed explanation). The modeled surface brightness for this components are listed in Table 5. We categorized the [C II] emission based on selected region in Table 3.
