[Halld-tagger] Fwd: Hall D Positions...

[Todd Satogata]

Hi folks,

Her are plots John sent me from some calibration activity on Tue
Oct 2 afternoon. AD00 shows a comparison of the 5C11B cavity BPM
to the AD00 stripline BPM with good fidelity; 5C11 shows a
similar comparison for 5C11 and 5C11A BPMs. I will be in tomorrow
morning to double-check with no bleedthrough after Hall C shuts
off, but we believe we are in shape for the nA BPMs to support
orbit lock at low current for tomorrow's TAC run.

                                                 -Todd
