A temporal analysis of the noise is performed, and non linearities are taken into account. We then extend the correlation method to groups of several pixels to derive the interpixel capacitance of a detector, found to be x = -0.0263 +/- 0.0020 (stat) +/- 0.0040 (syst). All measurements are consistent to a sub-percent accuracy.
