keyword=Issues remains & Full Scalar consistency check added to online plots
scalar consistency check, which calculates difference between bigbite
scalar counts and ones on LHRS, has been added to expert online
display, online("scalar",run#). (as shown below)
The check includes 12 channel of counts
T1, T3, T5, T6, L1 Accept, 103kHz fast clock, u1, u3, u10, d1, d3, d10
On 5 scalar pairs
ungated, spin,hel= ++, +-, -+, --
The issues previously reported still persists:
1. bigbite is constantly counting ~1% less T3 than LHRS on all 5 scalars
2. LHRS (spin=-1; Hel=-1) is missing 10^-4 counts on all channels.
