• these should be sensible for any detector

• "There are 4 2x1 sensors that do not work. There is also a single 2x1 slot on one of the PCBs that has a bad connection. So the sensor works, but we can't operate it.
• The inner, beam-side 2x2s have tungsten shields, but only one other 2x2 does. Many of these modules were used during Run3 and so have some radiation damage and chipped sensors." - from Chris
