keyword=helicity scheme - direct reporting
Per request of Hari Areti the helicity scheme was changed to direct reporting.
- pseudo-random quartet
- non-line synchronized
- direct reporting (not delayed).
See e-log 1159141.
For hall A this affects online packaging of scaler data. To accomodate the
direct reporting I recompiled the VME code with OUT_OF_TIME_MODE=0
and rebooted the VME crates. To test that all was ok, I observe that the helicity
which goes via a V-to-F into channel 32 of normalization scaler will count a
nonzero rate for one helicity and a zero rate for the other helicity, in xscaler,
which is a consumer of the packaged data. Note, this is only a test of direct
reporting since the helicity flag is used as "data" in this case and is by definition
