keyword=Gas cherenkov performance
Position dependence of gas cherenkov performance has been analyzed. In the following plots please find adc_sum_t vs. x_geom for each mirror. The photo-electron number for right arm mirror #7 is a little bit lower than the average, but it's okay. No other problem has been observed.
Because the HV setting has been changed this morning, waiting for good run (need to change polarity) to re-calibrate the left arm gas cherenkov.
