    keyword=HAND: The Good, the Bad, and the Ugly

    The Good:
    · V-22L (21 counting from 0) looks good again! Horray! (see Figure 1)
    · The 4 PMTs in Plane 3 (N3-11L, N3-12, N3-11R, N3-12R) are no longer saturated! ...but...

    The Bad:
    · 3 of the TDCs from Plane 3 are no longer showing (see Figures 2 and 3). We went down in HV too much! Oops...going to raise them back up between runs

    The Ugly:
    · The ADC for N2-5L (4 counting from zero) has disappeared (Figure 4) but the TDC is still good (Figure 5)
         → While in the Hall, I accidentally dropped a small connector inbetween the ADC wires. It's entirely possible that I accidentally knocked the cable for this one and it just need to get pushed back in.


    Other than that, all looks well for the HAND.
