Example of the spectral subtraction for the Hα line of SSTc2dJ160830.7-382827. The target spectrum normalized to the local continuum is represented by a solid black line, while the best-fitting BT-Settl spectrum is overplotted with a dotted red line. The difference spectrum is shown in the bottom of the panel, where the residual Hα emission is highlighted by the hatched green area.
