    keyword=Run 1471: Cerenkov TDCs vanish for both T2 and T6 events

    We applied cuts to see if we could recover the Cerenkov TDC signals. Fig. 1 shows the regular Cerenkov TDCs; Fig. 2 shows the group Cerenkov TDCs. The top pane of each figure shows T2 events and the bottom pane shows T6 events.

    As we saw in Post 261377 (without the cuts), the individual TDCs are uniform and there are small peaks in the group TDCs.
