Problems List:

1, S1 TDC: some channels are a little noisy. Maybe because of EDTM
signals. Vince told me there is a flag D.edtmbb to cut off EDTM but it is
not working right now. Anyway, it looks like it is not a big deal

2, S2m ADC: Multi-peaks, or empty channels are gone if Ped. substraction
is off, but it seems that there are not many high-photon electron
signals, or says, no big signals when high energy electrons pass through
scin.

3, Cer TDC: Noisy. We should take a run without EDTM to see whether they
are because of the signals.

4, VDC Wires: It does not look as what we see during cosmic ray runs. Is
that because of the Quadro-poles are off?

5, Pion Rejectors: As usual, there are some missing channles,
PR1#18,#19,#20,#33, PR2#16,#17,#32,#33,#34 are empty or low statistic,and
PR1#21 is always very noisy. Some of them are in the two ADC connectors.
I will check the connectors. However, Pion Rejctor works well so far to
seperate electrons and pions.
