Notes.

(a)

Name of sources starting with numbers (e.g., 18151−1208) refer to the IRAS name (Neugebauer et al. 1984).

(b)

Systemic velocity (VLSR) derived from the hyperfine fit to the N2H+ (1–0) and C2H (1–0) lines (see Sect. 3.1).

(c)

Sources classified as IR-luminous (IRL) or IR-dark (IRD) according to its emission or not at mid-IR wavelengths according to López-Sepulcre et al. (2010).

(d)

Parameters obtained from the single-temperature, modified black body fit to the spectral energy distribution (see Sect. 3.3).

(e)

Bolometric luminosity derived by integrating over the full observed spectral distribution (see Sect. 3.3).

(f)

Observed simultaneously with (in the same map as) 18507+0121.
