keyword=L1A delays of both two HRSs have not been change since Mar4.
I looked at my note and also the trigger files in atrig@adaql5:/trigger/,
and I found that actually I did not change the delay values of L1A when
switching from SRC to x>2 experiment. The last modification date of
trigger_left.map and trigger_right.map was Mar. 4th. I can not remember
whether at that time we thought we did not have to change the delays or
we changed the L1A delay at the bigbite weldment. Alexandre and I set up
two scopes for two HRSs to check the trigger timing. You might want to
bring up those two screen through the website and you should see whether
the retiming function works properly or not. Alexandre knows the IP
address for both.
I don't know why there is a 60ns shift. My suggestion is still not to see
the RAW TDC values but check the real timing you care, before you take an
access to check connections.
