get_radial_velocity

sunkit_image.asda.get_radial_velocity(gamma, rcore, ratio_vradial, r=0)

Calculate radial (expanding or shrinking) speed at radius of r.

Parameters:

• gamma (float, optional) – A replacement for vmax and only used if both gamma and rcore are not None. Defaults to None.

• rcore (float, optional) – A replacement for rmax and only used if both gamma and rcore are not None. Defaults to None.

• ratio_vradial (float, optional) – Ratio between expanding/shrinking speed and rotating speed. Defaults to 0.

• r (float, optional) – Radius which defaults to 0.

Returns:

float – Radial speed at the radius of r.
