Abstract
We consider how to analyze microcalorimeter pulses for quantities that are nonlinear in the data, while preserving the signal-to-noise advantages of linear optimal filtering. We apply the approach to compute the electrothermal feedback energy deficit (the Joule energy) of a pulse, which has been proposed as a linear estimator of the deposited photon energy.
