Fig. 4.

Spectral comparison between MoCA (black line) and the semi-analytical Comptonisation model available in XSPEC as indicated inside the figure. Upper panel: case of a slab corona with τ = 5 and kTe = 50 keV observed at an inclination of 60°; lower panel: case of a spherical corona with τ = 4 and kTe = 40 keV at the same inclination. In the latter case we performed the comparison with Nthcomp as well.
