P3 y calibration
Not yet sure why the calibration constant for P3 is different, will check the transfer matrix with Javier, might be due to asymmetry caused by broken x-strip, but that’s probably just a total guess!
P3y variation as ZH4X is varied
The variation here is 20 times larger than in P1 and 5 times larger than in P2, cannot believe this is due to rotation error in P3, maybe dead strip?
P2x x calibration
Previous week’s calibration constant here was about 0.01, half of what is expected, now it is half that again, suspect I need to check transfer matrix with Javier, but as this was the damaged processor, I will also check the output in case this is (partly) a hardware issue.
