Notes. The columns are as follows. Name: ATLASGAL source name; Class: source classification based on König et al. (2017); Tpeak1−0: [C I] 492 GHz peak main-beam brightness temperature; Tpeak,2−1: [C I] 809 GHz peak main-beam brightness temperature; FWHM1−0: [C I] 492 GHz line width; FWHM2−1 : [C I] 809 GHz line width; Tex: excitation temperature; −1−0: [C I] 492 GHz opacity; −2−1 : [C I] 809 GHz opacity; N(C): [C I] 492 GHz-based column density of atomic carbon. For the five sources where [C I] 492 GHz only is detected, upper and lower limits on the relevant parameters are indicated as the downward and upward arrows. In the case of G338.78+0.48, the measured Tpeak1−0 is most likely a lower limit, since its [C I] 492 GHz spectrum is affected by a contaminated reference position.
