LineBroad

class sherpa.astro.models.LineBroad(name='linebroad')

Bases: sherpa.models.model.ArithmeticModel

A one-dimensional line-broadening profile.

ampl

The amplitude of the line.

rest

The rest wavelength.

vsini

The rotation velocity (v sin(i)), in km/s.

Notes

The model is:

f(lambda) = 2 * ampl * c * sqrt(x) / (pi * rest * vsini)

        x = 1 - ((lambda - rest) * c / (rest * vsini))^2
