Results from various model fits to o-H₂S for V1300 Aql (top) and IK Tau (bottom). Transition numbers at the top of a column indicate the line for which the parameters are plotted. The top row of the plot of each star shows the tangential brightness distribution of the emission line, I_bri, scaled with the radius squared, r², to emphasise the features more clearly plotted against radius. The corresponding bottom row shows the tangential optical depth of the emission line with radius. The legend in the top right is given for V1300 Aql and also applies to the more sparsely selected lines for IK Tau.
