Notes. Model A represents a “standard” spherical wind, similar to the assumption of Panagia & Felli (1975), but as a conical “jet” with a given opening angle. Model B describes an adiabatic spherical wind and Model C an adiabatic collimated wind. The opaque spectral index (i.e. for the optically thick wind) αop is defined as
