In order to highlight the 2D shape differences, a 2D-overscan correction is applied. A few exposures illustrating the variations of the 2D shape for an instable CCD are shown below. The 2D shape of the image in amplifier C01 is different in the 3 cases.

In order to quantify the number of e2v instable amplifiers, a stability metric *d* is defined from the eo_pipe stability task data products. More precisely, *d* is defined, for a given amplifier in a given run, as the difference between the 5th and 95th percentiles of the image mean over all the exposures. The distribution of *d* for run E2136 is shown below. Applying a threshold at 0.3, 51 amplifiers are identified as instable (see the corresponding mosaic).
