Const1D
(name='const1d')[source] [edit on github]¶ Bases:
sherpa.models.model.RegriddableModel1D
,sherpa.models.basic.Const
A constant model for one-dimensional data.

c0
¶ The amplitude of the model.
Notes
The functional form of the model for points is:
f(x) = ampl
and for an integrated grid it is:
f(xlo,xhi) = ampl * (xhi - xlo)

guess
(dep, *args, **kwargs) [edit on github]¶ Set an initial guess for the parameter values.
Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.
