- Pass1
  - mechanics/schedule (Joe) - code/scripts ready to start by 11/18, but may wait for RS time calibration.
  - acc/rej(stlay) (Shaomin) - increase in events rejected by UTC reconstruction cut and Pdc>280 cut during period when IC discriminator was reduced to 10ns.
- 1997 pnn2 (Bipul) - rerun 3 tapes of 1/3 sample to refit CCD pulses. More rejection is possible. Working PbG does not give more rejection.

  - Note on RS scintillator thickness
  - RS counters in UMC
- RSMON
  - Ntuple discription (Kentaro)
  - one PMT gain change of ~65% in middle of one spill (Jim)
- TD energy (Tetsuro) ( This study was done with Fitpi3, and will be redone with Fitpi4 )
  - bad stopping counters (will be cut in Pass1)
  - pi->mu energy in 1998 L6-12 is OK at 3.05 MeV, but 1998 L13-18 and 2002 all layers is only 3.0 MeV
  - pi->mu energy is dependent on muon time (low from 15-60ns)
- Energy (Shaomin)
  - Kp2 high energy tail appears to be due to high rate (not kaon or muon decay time)
  - Kp2 energy tail is also correlated to K/pi ratio
- BVL rate (Laurie) - BVL TDC rate is 20 MHz

- Collar: Oleg has observed 20% less light yield from usCO compared to dsCO (could be degradation with time, could be less to start with). He measures 30-35 p.e./MeV and estimates 20 p.e./MeV in the detector after light guides ,etc. This is comparab le to the old CO. He then argues that light yield probably has little effect of PV inefficiency and that Lrad is most important -> and that we should install the new usCO. Marat is starting to look at the CO's in 2002 from pnn1or2 ntuples and plans to sta rt by calibrating T0's.
