Detailed Description

The payload telling which PXD pixel is dead (=Readout system does not receive signals)

There are multiple reasons for dead pixels: 1) Brocken (open) drain line (-> current cannot flow into DCD channel) 2) DEPFET current into DCD out of dynamic range 3) DHP subtracts too high pedestal correction 4) ...

Here, we cannot distinguish the true reason, but report that a pixel gets never hit during some IoV.
