Spectral fits for selected optical (left) and NIR (right) lines using the clumping law Linear_10–050. Observations are shown in black, and best fit model profiles in red. We stress that the individual model parameters for the best fitting optical and NIR profiles differ (to various extent) since the analyses have been performed separately for both ranges (cf. Table A.1 vs. Table A.2). The horizontal bar gives the wavelength scale for each range, and the scale of the ordinate axis is given by the vertical bar (at the bottom of the H_α column for the optical range, and at the bottom of the Br₁₀ column for the NIR.)
