Notes. Col. (1) source names, which are also its Galactic coordinates. If one region has multiple cores, they are given suffix numbers “(1), (2), (3)...”.Col. (2) excitation tempearture of the ¹²CO (1 − 0) at the emission peak of the core.Col. (3) H₂ column density at the emission peak of the core.Col. (4) effective radius of the core, which is calculated from using where A_core is the area encircled by the 50% contour in the ¹³CO (1 − 0) map (in unit of pc²). Col. (5) flux of the radio continuum emission associated with the core. The values are extracted from several works, including the 6 cm (^m) MAGPIS survey (Helfand et al. 2006), and the observations of (^g) Gregory & Condon (1991), (^r) Rodriguez et al. (1981), (^k) Kurtz et al. (1994), and (^w) Walsh et al. (1998). The observational wavelength is λ = 6.1 cm for Gregory & Condon (1991) and Rodriguez et al. (1981), λ = 3.5 cm for Kurtz et al. (1994), and λ = 3.5 cm for Walsh et al. (1998). The detection limit is σ ≃ 2.3 mJy for MAGPIS and σ ≃ 6 mJy for Gregory & Condon (1991). Col. (6) infrared emission feature associated with the ¹³CO cores as shown in Fig. A.1. For the cores associated with the IR emission, the emission features are classified as “point-like” (p) and “diffused” (d).
