¹²CO, ¹³CO, and [Ci](1–0) transitions for NGC 1140. Top row: ¹²CO(1–0), ¹²CO(2–1) (IRAM), and ¹²CO(3–2) (APEX); second row: ¹³CO(1–0), ¹³CO(2–1) (IRAM), and ¹²CO(4–3) (APEX); third row: [Ci](1–0) (APEX). As in Fig. 1, the baselines are shown as a horizontal solid line, together with the multiple-component Gaussian fits as described in Sect. 3.3. The vertical axes are in units, while in Table 4 the units are T_mb, converted from as described in Sect. 3.3. Velocity channels are as reported in Table 2. The red curves and lines refer to 30-m spectra, while the blue ones to APEX.
