Blue and red line wing ratios of CO 10–9/3–2 (top panel), H2O 110–101/CO 10–9 (middle panel), and H2O 110–101/CO 3–2 (bottom panel) for the composite Class 0 and Class I source spectra. The H2O/CO 10–9 and H2O/CO 3–2 ratios are a factor of two lower than shown in Fig. 4 due to the beam size difference of 20″ (CO 10–9 lines) to 40″ (H2O 110–101 lines).
