OnionExpShellModel

sans.models.OnionExpShellModel

class sans.models.OnionExpShellModel.OnionExpShellModel(n_shells=1)

Bases: sans.models.BaseComponent.BaseComponent

This multi-model is based on CoreMultiShellModel with exponential func shells and provides the capability of changing the number of shells between 1 and 10.
