Scale2D

class sherpa.models.basic.Scale2D(name='scale2d')

Bases: sherpa.models.basic.Const2D

A constant model for two-dimensional data.

This is a specialized form of the Const2D model where the integrate flag is turned off.

c0

The amplitude of the model.

Box2D, Const2D, Delta2D, Scale1D

Notes

The functional form of the model for points is:

f(x0, x1) = ampl

and for an integrated grid it is:

f(x0lo, x1lo, x0hi, x1hi) = ampl * (x0hi - x0lo)
                                 * (x1hi - x1lo)

This later case will only be used if the integrate attribute is set to True.
