2.5W PS unstable perhaps? Worth measuring on next maintenance day maybe...

Figures 1 and 2 show the settings after MOLLER beam studies yesterday afternoon - see linked entry.

The RTP HVs are slightly different (due to different PITA2, -6257 instead of -4745) than before the beam studies.

Will ask MCC to change PITA2 back to -4745.
