pygsti.extras.rpe.rpetools.extract_epsilon

extract_epsilon(model, rpeconfig_inst)

For a given model, obtain the angle of rotation about the “loose axis”

WARNING: This is a gauge-covariant parameter! Gauge must be fixed prior to estimating.

Parameters:

• model (Model) – The model whose angle of rotation about the “loose axis” is to be calculated.

• rpeconfig_inst (RPEconfig object) – Declares which model configuration RPE should be trying to fit; determines particular functions and values to be used.

Returns:

epsilonVal – The value of epsilon for the input model.

Return type:

float
