[Halld-offline] Monitoring Launch 2023-01 ver06

[Beni Zihlmann]

I should be more specific:

regarding the tagger hodoscope: most runs are fine and only a few counters
are slightly off.  and only two runs show a significant number of 
counters that are
off (I guess because statistics issues). This I can fix easily I guess.

regarding the microscope: here there are quite a few runs where it seems 
the issue
is in the walk correction, making the picket-fence peaks wider and very 
asymmetric.
this can only be fixed with redoing the walk correction and then after 
that once
can again look at the constant offsets.

cheers,
Beni
