Hi, all,
Just found that the blast.sc_cal file in blast Blast_Param is over written
by a dummy at a certain point. Do not know who did this and the time stamp
does not reflect this incident. all tof tdc offsets in that file are 0.
replaced it with blast.sc_cal.save in the same directory. Noticed that it
is difference from the one in CVS. Some one should decide which one is
good and synchronize them. the bad file is copied into blast.sc_cal.BAD
with time stamp preserved.
all data crunched after July 8th are bad. sympton is ttl-ttr for
left+/right- events peaks are 700 channels instead of 200.
Vitaliy, Aaron and anyone who is doing analysis on these runs, which
include all the 2-cycle deuterium runs, you may want to stop and wait for
them to recrunch if your analysis depend on any cuts that is sensitive to
timing.
It sure fucked me up badly.
Chi
