Velocity field and spectra in VV 114 E SW-s2. Left: E_low-velocity diagram for the CO P branch lines in VV 114 SW-s2. Contamination by adjacent ¹³CO (together with C¹⁸O) and H₂O lines is indicated on the red side of the profiles. The numbers on the left side indicate the rotational quantum number J of the lower level. Middle and right: comparison of the profiles of several CO and H₂O ro-vibrational lines (in yellow and light-blue, respectively) and the profiles of CO v = 0 J = 3 − 2 line observed with ALMA (green, with a Gaussian fit to the line profile in red), and of several lines of H₂ (pink) and hydrogen recombination line (brown). Prediction by our composite models for the ro-vibrational lines is overlaid.
