pvtend.interp_event_field_to_single_theta

pvtend.interp_event_field_to_single_theta(theta_3d: ndarray, field_3d: ndarray, theta_target: float) → ndarray[source]

Interpolate one 3-D field onto a single θ surface → (ny, nx).

Vectorized linear-in-θ interpolation. Equivalent to one slice of interp_event_fields_to_theta().
