Optimization of the multiple sampling and signal extraction in non-destructive exposures
Using the full covariance matrix of correlated readout and shot noise in a least squares fit improves signal-to-noise by about 5-7 percent and cuts the y-intercept noise by up to 60 percent for non-destructive infrared ramps.
