Bases: BaseVectorRegularization

Base amplitude regularization class for models defined by vector quantities.

The BaseAmplitude class defines properties and methods used by amplitude regularization classes for vector quantities. It is not directly used to constrain inversions.

mapping	Mapping from the inversion model parameters to the regularization mesh.
model	The model parameters.
mref	reference_model.mref has been deprecated.
nP	Number of model parameters.
