pystrata.variation.ToroVelocityVariation

class pystrata.variation.ToroVelocityVariation(ln_std: float, rho_0: float, delta: float, rho_200: float, h_0: float, b: float, vary_bedrock: bool = False)

Toro (1995) [T95] velocity variation model.

Default values can be selected with generic_model().

Parameters:

• ln_std (float, optional) – \(\sigma_{ln}\) model parameter.

• rho_0 (float, optional) – \(ρ_0\) model parameter.

• delta (float, optional) – \(\Delta\) model parameter.

• rho_200 (float, optional) – \(ρ_200\) model parameter.

• h_0 (float, optional) – \(h_0\) model parameter.

• b (float, optional) – \(b\) model parameter.

• vary_bedrock (bool, optional) – If the velocity of the bedrock (half-space) should be varied.

__init__(ln_std: float, rho_0: float, delta: float, rho_200: float, h_0: float, b: float, vary_bedrock: bool = False)

Initialize the model.

Methods
