gcmotion.Profile.findPtheta

Profile.findPtheta(psi: Quantity, units: str) → Quantity

Calculates Pθ(ψ). “Pzeta” must be defined.

Only applicable in the absence of perturbations.

Parameters:

psiQuantity

The psi Quantity.

unitsstr

The Ptheta units. Must have dimensionality of canonical momentum (orbital momentum = [energy] * [time]),

Returns:

Quantity

The calculated Ptheta Quantity.
