keyword=General performance of gas cherenkov detectorsHere is a plot for gas cherenkov detector performance:
horizontal axis is spec_l(r).gas.xdetgeom, vertical axis is spec_l(r).gas.adcsum_t
(A) top: right arm gas cherenkov, looks good, about the same as what it was before;
(B) bottom: left arm gas cherenkov,
(1)photoelectron number for each mirror is much higher than what we had before, thanks for the extension;
(2)PMT #7 (or #8?) has become the best one;
(3)Do we need to lower the high voltage?
