A power law may be used to describe:

\[y = ax^b + c\]

where: - a - magnitude - b - exponent - c - is a constant


An example of when this might be used is for spin relaxation modelling [1].

Properties (fitting parameters)

Name Default Description
Magnitude 1.0 coefficient for linear term
Exponent 1.0 exponent
Constant 0.0 coefficient for constant term
