Modeled emission of C₂H₅OH in red, overlaid over the observed spectrum (filled black histogram) and the global model including all molecular transitions in this study. Only the 18 brightest transitions or group of transitions according to the LTE model of C₂H₅OH are displayed, ordered in descending order of brightness from left to right and top to bottom. The model generated with MADCUBA makes use of the spectroscopic parameters in JPL catalog entry 46004. The frequency of the brightest transition in each panel are displayed for reference.
