Detailed Description

Variant of Schwarzschild density data object based on spherical-harmonic expansion of potential coefficients at radial mesh points.

Only even non-negative harmonics in l,m are used because of triaxial symmetry. Nang is the expansion order (lmax), and the number of coefficients at each radius is (Nang/2+1)*(Nang/2+2)/2 Note: the potential in which the model is evolved, needs not to be itself a spline expansion, but if it is, then the model coefs are initialized from the potential rather than by computing integrals over density (which are expensive).

Member Function Documentation

double smile::CSchwDataDensSHMesh::getConstraintNormFactor ( size_t  ) const

virtual

return a scaling coefficient which is used to normalize the penalty for constraint deviation in the optimization problem.

Introduced to make the optimization problem more uniformly scaled (//optional, by default returns 1)

Implements smile::CBasicSchwData.
