1>Raw Data vs ZS Data @Run15
Data | Raw Data | ZS data |
Settings | Run No: 16045104 Data Mode: Raw Data Mode Pedestal:16015052 Noise Table: offline/hft offline cuts:default settings With CMN suppression Masking : 1 Used Dynamic Masking : mDynamicMask=1 2 Do basic noise channel masking: if(intrinsic_noise>10) continue; 3 with hot chip masking: if (gStSstDbMaker->chipHot(id_side, ladder, i, j / 128)) continue;

Run No: 16045118 Data Mode: ZS Data Mode Pedestal: ?? Noise Table: No Noise Table offline cuts:default settings No CMN suppression Masking : 1 Do basic noise channel masking: if(rms>10 || rms<1) continue; where rms is the directly from pedestal run, it is not intrinsic noise . It was applied in hardware level.

ps: the left and right plots have different scale.
Comments:
1 The charge matching in ZS data mode is boarder than Raw data.
2 ZS data also have higer ADC value, you can clear see a lot of hits have ADC value more then 300 ADC, some hits reach to 1000ADC . But in Raw data, almost all hits with ADC less than 300 ADC.
The reason should be relate to the pedestal shift and CMN shift. form Run14, the pedestal shift can reach several hundred ADC, and the CMN shift also changed event by event.
All Raw Data:
Run 16045104 to 16045117
