   Bases: :py:obj:`_WwPpSample`, :py:obj:`ProbeOutputKind`, :py:obj:`_DerivativesKind`


   Vector-valued derivative probing: the residual is a list of ``d`` order-leading arrays.
   ``sample = (ww, pp)``. Probe has both a mode and an order axis, so ``weight`` is the full
   ``omega[mode, order]`` matrix (a row = per-order, a column = per-mode, a matrix = both).
