    keyword=LHRS BPM/Raster Problem Probably Fixed

    I think the BPM/raster problem for the left HRS is now fixed. The NIM crate for the amplifiers was turned off in HRSH_RR5 electronics rack. Alexandre and I traced the cables to the top crate in this rack and discovered it was off. I checked spot_L with left arm run # 1345 (see Figure 1). It appears the BPMA x and y have a large offset. This should be checked with beam, and we should problem do a pedestal run for the BPMs.
