keyword=some shifted VDC data L-arm
Roughly 2 % of events have shifted time data in VDCs on L-arm.
I think this is because of missed S0 signal used for retiming but the
S0 rate is only 4 kHz, the width 100 nsec, so this can't be pileup.
There are much fewer such events on R-arm which has a traditional setup.
