keyword=BPM Pedestals

Here is the analysis for the BPM pedestal runs taken today with the
"new" and old attenuator modules being used in the LHRS. These
values should be compared to the numbers obtained back in October
(see Halog Entry 210522<\a>).

The values for the RHRS and original attenuator agree pretty well
with the old pedestal values.
