Fig. 11

Toy model for the narrow emission lines, obtained by considering an electron density 1013 cm-3 and three different temperatures along the accretion column (8000, 10 000, 23 000 K). The rotationally broadened standard star spectrum is shown in grey, and the individual lines are shown in various colours. The final model, including a constant veiling, is obtained by summing all three components.
