- Mode-10 Update
  - Mark had suggested to change the pulse amplitude threshold in hcana
    - is 10mV in hardware
    - was 5mV in hcana
    - changing amplitude threshold in software doesn't seem to work
  - weird difference between FADC and hcana in PuseTimeRaw (different plot
     scaling?)
    - PulseAmpRaw, Pulse IntRaw look very similar

- *Suggestions*
  Huber: Eager to see what physics Mode-10 data look like, comparing high and
  low rate runs

- Analysis of EDTM Study #2
  - currents were 10uA, 55uA, various PS1,2,3,4

    Run 13898: TLT=1.002, 55uA, PS2=8, PS4=5
    Run 13900: TLT=0.918, 55uA, PS2=8
    - apparently this can make sense, since the HMS EDTMs block the SHMS EDTMs,
      due to their lower PS.
  - can separate the HMS, SHMS EDTM timing distributions by doing a fit, since
      the individual shapes are known from other runs

    Run 13905: TLT=1.047, 100Hz EDTM rate
    - need to investigate this more.
- *Task for JM*
  - will think about writing an MC to understand these data

- Richard's EDTM Study w/o Beam
  Run 14140: Three EDTM 1kHz time raw peaks observed
  - not seen in regular LUMI runs

- * Question for future study*
  - can these extra peaks be reflections that maybe are part of the TLT>1
    problem?

- Looking at Q2=0.38, 0.42 Heep data (Summer 2019)
  2.7 GeV: 1 coin, 6 singles setting
  3.6 GeV: 1 coin
  4.5 GeV: 1 coin
  - for one run, the data doesn't look like a Heep run, so this needs to be
    checked

- * Suggestions*
  - need to recheck beam energy and angles in STANDARD.KINEMATICS
