DataModelInterface.discretize_systematics(z: float, sys_params: Sequence[float] | dict[str, float]) → tuple[tp.PowerType, tp.PowerType][source]#

Compute the discretized systematic power.

This outputs an approximation of the integral of the theory power spectrum over each cylindrical k-bin. The way in which this is done is controlled by window_integration_rule.
