    keyword=Right arm group 5-8 missing electron triggers

    Using run 4872 I found group 5-8 do not have electron triggers (both narrow and wide), in TDC spectrum. The TDC shows Preshower output from the medium-threshold discriminator is missing for these 4 groups.

    Xscaler also show zero rate from these 4 groups.
