Bases: sherpa.models.basic.Const1D

A constant model for two-dimensional data.

c0

The amplitude of the model.

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)
