Exp10
(name='exp10')[source] [edit on github]¶ Bases:
sherpa.models.model.RegriddableModel1D
One-dimensional exponential function, base 10.
-
offset
¶ The offset of the model.
-
coeff
¶ The scaling factor.
-
ampl
¶ The amplitude of the model.

Notes
The functional form of the model for points is:
f(x) = ampl * 10^(coeff * (x - offset))
and for an integrated grid it is the integral of this over the bin.

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.
