CrosstalkSolveTask¶
CrosstalkSolveTask
fits the crosstalk coefficients based on the full set of input flux ratios.
Processing summary¶
CrosstalkSolveTask
runs these operations:
Combines all of the individual exposure flux ratios measured by
CrosstalkExtractTask
into one set.Fits each pair of sourcetarget amplifier pairs to find the clipped mean value.
Optionally prunes coefficients that have coefficients that are statistically consistent with the flux ratio noise.
