Fig. 16.

Distant covariances, averaged over the 16 channels. Top: average value of distant covariances as a function of flat field average. Middle: average of covariances as a function of angle, that shows no excess in the serial direction (angle = 0). Bottom: covariances along the serial direction, that do not exhibit any obvious structure on top of the decay expected from electrostatics.
