    keyword=RHRS VDC efficiency from cosmic run 21848

    Attached are plots for the VDC efficiency and hits for RHRS. This morning Bogdan swapped the outputs for the HV supplies for the U1/V1 plane with the U2/V2 plane. It seems like the high voltage supply is the problem since now U2/V2 have low hits/efficiency. Jack is taking a look at it now.
