Example spectral line energy distribution used for fitting the temperature toward the blue lobe of outflow A. The data (black circles with errorbars) are at CO transitions (3–2), (4–3), (6–5), and (7–6). The model fits (dotted and solid line) from RADEX also include CO (5–4). The dotted line represents the best fit (χ² = 1 ± 0.05) SLEDs fromthe RADEX grid. The solid line represents the average value for these best fit models in (for this example) SLED. This fit gives T_kin = 66 K.
