Class and construction: SersicModel.

SersicModel.density_3d_VM20(r_pc)[source]#

Vitral & Mamon (2020) 3-D Sérsic density approximation.

Notes

Inputs and units. r_pc is scalar or an array in pc; n and re_pc come from stored parameters.

Returns and shape. Unit-integral tracer density in pc^-3 with input shape.

Validity. 0.5<=n<=10; 1e-3<=r/re<=1e3; positive finite r.
