Spectra along three representative lines of sight from the GOT C+ inner Galaxy survey showing T_mb, the main-beam temperature, versus V_lsr. The upper panel for each line of sight shows the [C ii] spectrum along with the fits derived from the Gaussian decomposition (shown in red). The lower panel for each line of sight shows the corresponding H i in black, ¹²CO in blue, ¹³CO in red, and C¹⁸O in green. The scalings for T_mb are shown in each panel.
