keyword=PMT#04 in BB Cherenkov seems badRun 5143 was a cosmic run which I used to check pedestal. I just looked at the ADC signal without any cut. Other channels look reasonable except PMT# 4 $ PMT17. PMT17 we knew it is bad for long time. But now it seems PMT#4 is also died. To compare with nomal one, I also put PMT#19 into log.
