    Took data with Pockels cell off to quantify false asymmetries from
    electronics pickup.

    Did a Hall C IA scan (with Pockels cell off) to determine the slope for
    doing Hall C beam charge feedback. The slopes are +250 ppm/V for both
    half wave plate states. [12350 and 12351]

    A rotating half wave plate scan was done and it was decided to stay at
    the current RWP setting of 1200 (30 degrees.) [12352 and 12353]

    Did a Hall A PITA scan and got slopes of -5.1 ppm/V and +4.9 ppm/V for
    HWP IN and OUT respectively. [12354 and 12356]

    Yves tried some new quad settings that produced bigger position
    differences with broader distributions. [12358]

    Measured the Hall C charge asymmetry (PC on) and found it small ~8 ppm.
    Did this again with CIA=7 and found Hall CA went up to 460 ppm. [12358
    and 12359]

    Measured the Hall C PITA slope for IHWP OUT and got -4.6 ppm/V (which is
    opposite to our PITA slope for ihwp out) [12361]
