Followups:

• 346243 02/09/11 20:57 V. Sulkosky EDTM Setup Slightly Changed both HRS's
• 346244 02/09/11 21:07 yez L-HRS: missing VDC-V plans is due to a wrong maps; this problem is fixed

As you can see from those graphs bellow, there are several issues:

1,TDCs of s1,s2m,cer do not show the correct distributions as we have
last week. What changed since last week is that we have an all-in-one DAQ
system and the L1A is sent from TS in Bigbite weldment, and people who
working on FPP re-arranged the ADC&TDC modules in ROC4, where all the
TDCs of s1,s2m and cer are in. 

The ADC issues of s2m may or may not relates to the EDTM signal. I asked
Vince to turn off EDTM signals and take a pure cosmic ray data, after he
finishes his work.

I am not sure whether is the wrong timing because of the new DAQ setup,
or the ROC4 has not been fixed completely. 

2, V plans of VDC are missing all infomation. The strange thing is that
even though ROC4 has a problem, it should not affect V plans, since
ADC&TDC modules of them are in ROC3.
