4.1.36. Vblo: rectangular velocity broadening model

This multiplicative model broadens an arbitrary additive component with a rectangular Doppler profile, characterized by the half-width v. Therefore if a delta-line at energy E is convolved with this component, its full energy width will be 2Ev/c, and line photons get a rectangular distribution between E-Ev/c and E+Ev/c. Of course, any line or continuum emission component can be convolved with the this broadening model.

The parameters of the model are:

vblo : Velocity broadening half-width v, in km/s. Default value: 3000 km/s.
