helicity latched-charge is not populated for some datasets

[c-dilks]

We started adding helicity-latched charge to the QADB when we produced the RG-C QADB. We have not gone back to older datasets and populated helicity-latched charge for those, unless requested by the Run Group.

If you need helicity-latched charge for a dataset and we do not provide it in the QADB, please ask.
