Spatially integrated emission spectra of the [C I] J = 1−0 line at 492.165 GHz for the seven sources in our sample. All the spectra are shifted to their respective local standard of rest velocity (Table 1). The shaded region marks the 1σ uncertainty for each source. The spectrum of AS 205 A is shown in gray with FM Cha as a reference of the typical linewidth for a modestly inclined disk. “N” and “S” depict the V_lsr of AS 205 Ν and AS 205 S, respectively.
