Power Law

Description:

#power_law model #conversion of PowerLawAbsModel.py #converted by Steve King, Dec 2015

This model calculates a simple power law with a flat background.

Definition

$$ I(q) = \text{scale} \cdot q^{-\text{power}} + \text{background}
$$
Note the minus sign in front of the exponent. The exponent *power* should therefore be entered as a **positive** number for fitting.

Also note that unlike many other models, *scale* in this model is NOT explicitly related to a volume fraction. Be careful if combining this model with other models.

References

None.
