Class and construction: SersicModel.

SersicModel.density_3d_VM20bis(r_pc)[source]#

Official Vitral & Mamon (2021) VM20bis 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<=3.4; 1e-4<=r/re<=1e3; positive finite r.
