Sun Mar 12 09:15:00 2023, EG, Other, , , Array_monitors mat refresh synchronization
|
Beam stable, counting rate within limits, plunger distance within the given tollerance, gamma spectra ok, everything looks good but....
(yes there must be some "but"), refreshing of EAGLE_array_monitor.mat and NEDA_array_monitor.mat are out of sync. Mostly pure red colour is dysplayed. Not very usefull and (I suppose) missleading information.
