Sin

class sherpa.models.basic.Sin(name='sin')

Bases: sherpa.models.model.ArithmeticModel

One-dimensional sine function.

period

The period of the sine, in units of the independent axis.

offset

The offset (related to the phase) of the sine.

ampl

The amplitude of the sine.

Cos, Tan

Notes

The functional form of the model for points is:

f(x) = ampl * sin (2 * pi * (x - offset) / period)

and for an integrated grid it is the integral of this over the bin.
