RadialProfile(std::string const &name, int defaultMaxRadius)
void registerBasis(std::shared_ptr< MultiShapeletBasis > basis, int nComponents, int maxRadius)
Register a basis with the profile, making it available to callers of getBasis().
std::string const getName() const
Return the name of the profile.
static RadialProfile & get(std::string const &name)
Return a predefined radial profile given its name.
virtual double evaluate(double r) const =0
Evaluate the profile at the given radius.
std::shared_ptr< MultiShapeletBasis > getBasis(int nComponents, int maxRadius=0) const
Return a multi-Gaussian approximation to the radial profile.
double getMomentsRadiusFactor() const
Return the 2nd-moment radius in units of the half-light radius.
ndarray::Array< double, 1, 1 > evaluate(ndarray::Array< double const, 1, 1 > const &r) const
Evaluate the profile at the given radius (vectorized).
