Since run 18537 (05-Nov-99), the detector is running with
modified camac lists that have the F19/T19 on the stop master commented.
I have checked two of the runs with the above camac list.
The latest is run 18551
unfortunately the problem in the Stop Master data still
exists: we have at least 11 events where the same thing
(the CIT SMT does not seem to be correctly inhibited by the
computer busy) happens.
The events have the same pathology: a cspam or a trigger
in the accompanying sm (of the same microvax) happens.
The SM in question receives the xstop (after around 1 millisec
and before the xSTOP clock receives its maximum value.
Then the CIT SMT trigger arrives when its clock has already assumed
its maximum value, HOWEVER , and CONTRARY to the manual ,
it is recorded in the Stop Master trigger
pattern, where both the CIT(bit1) and the fCIT(bit 11)bits are set.
In addition the clocks for the individual faces are started.
Obviously, the presence/absence of the F19 command was not affecting
these events.
