Some Broken Bonds when removed from freezer

When readout using _runNumberInSequence=66 got a strange pattern and thought this was due to broken bonds. It is infact due to the runNumberInsequence chosen not the broken bonds. CoB1 was then allowed to anneal for 24, 48, and 168 hours to see the differences

5Mrad scan conducted after annealing for 168 hours taking in all pixels
shows beam spot well

Noticed that there was much increased threshold for 5Mrad run and found that wrong cfg file used so it cannot be compared to earlier dose data. The annealing studies were however conducted with the same cfg file so annealing study still good

Following the easter bank holiday the sensor was removed from the freezer and allowed to anneal

After 6 weeks in the freezer due to traveling etc I know hope to conduct annealing studies on this sensor. How accurate they will be I am unsure but hopefully not much change over the 6 weeks in the freezer

Easy way to check.. perform a scan and compare to 5Mrad data before doing annealing

The fractional changes for CoB3 and CoB4 at 1 Mrad seem to be in agreeance. However 1500 krad exposure is scrap for many reasons. Therefore this sensor will now be abandoned
