"""
class to handle extended surface brightness profiels (for e.g. source and lens light)
all profiles come with a surface_brightness parameterization (in units per square angle and independent of
the pixel scale).
The parameter 'amp' is the linear scaling parameter of surface brightness.
Some functional forms come with a total_flux() definition that provide the integral of the surface brightness for a
given set of parameters.
The SimulationAPI module allows to use astronomical magnitudes to be used and translated into the surface brightness
conventions of this module given a magnitude zero point.
