Pixel arrays #1 - to #14 have metal only on top of the pad, while the
pixels from arrays #15 - #32 are totally covered in metal. In principal
this shouldn't change the breakdown voltage, but we are seeing that #15
-#32 show a higher breakdown voltage.
It can also be seen that we are using different p-stop designs for the
pixels, the effect of those remain to be checked. We are currently
collecting more data so that we can get statistics on the p-stop designs.
