Non-LTE plus LTE modeling for the CARMA-7 spectrum obtained from the best-fitting results (see Table 1). Line rest frequencies are indicated at the top of each subpanel. Rest-frame velocities and temperatures are labeled at the bottom and left-side positions in each subpanel. Observed spectra are shown in black, LTE modeling (narrow plus broad components) is indicated in blue, RADEX modeling is in green, and the combination of LTE plus RADEX emission is in red. An LSR velocity of ∼7.8 ± 1.0 km s⁻¹ (see Sect. 2.3, Fig. 1, and Table 1 for the used references, initially adopted and calculated V_LSR, respectively) was previously subtracted.
