Hi Sean,

the tagger microscope walk correction does not work for the CPP/NPP run 
(RunPeriod2022-05).
attached you can see two examples of tagger microscope column 19 where 
on the vertical
axis is the tagger time (with all corrections) minus the RF time and on 
the horizontal axis
is the signal amplitude.
As you can see the amplitudes in the CPP/NPP run are much smaller. I 
guess that is why
the walk correction does not work for the counter.
It's pretty much the same for all counters. All amplitudes are way 
smaller. I guess it needs a
dedicated walk correction calibration.

cheers,
Beni
