The sum of weights used to calculate Q-vector, for entire detector. This is phi-weighted This is useful if one wants to un-normalize the Q-vector ** note that this depends on "order," because the eta-weighting or ring-weighting can depend on order (user sets it) ** this stands in contrast to the ring-by-ring Qvectors, which do not depend on order. order order of the EP. Begins at unity (order=1 means first-order EP)
