MOLLIE radiative transfer results using the o-NH₃ fractional abundance profiles from Fig. 3, overlapped with the observed spectrum: (top) blue solid and dashed curves refer to the Crapsi et al. (2007) profiles, assuming an ortho-to-para NH₃ ratio of 0.7 and 1.0, respectively. (Bottom) The red thick curve refers to the Sipilä et al. (2015a,b) profile; the red thin curve is the same as the thick red curve, but divided by 2.
