Followups:
keyword=D3 on L-HRS double pulsingVince and Bryan noticed some end-of-run charge info for D3 on L-HRS
looked wrong, typically high by some amount. From examining the
rates during a run, I find that sometimes the rate on D3 is doubled
(see fig 1) and in general becomes flakey and noisy.
(U3 also looked funny but that was a scaler.map problem, fixed
this morning - halog 232201 -- easily recovered offline.)
Other observations:
1. All other correlations of currents look very linear, e.g. u3:d10.
2. R-HRS copy of d3 is clean, therefore the problem is local to LHRS.
3. The problem comes and goes. In some runs d3 looks fine.
I suspect the classic problem of a fatigued connector on a cable !
I will take access at next opportunity and check.
