Noise run analysis

1. General Information

During this run the ZS threshold was set to 3.6σ.

RUN Trigger Sequence Trigger Mode Frequency Events
56288 L2a BC 4000 Hz 1502
56286 L2a BC 40 Hz 1007
56287 L2a BC 400 Hz 1056

The reconstruction was performed with AliRoot v4-14-Release. The official OCDB files were used from AliEn. These files were produced from previous calibration runs.

The analysis of the SSD clusters revealed that we have the following number of golden clusters over all the events for the two runs:

RUN Layer 5 Layer 6
56288 513 680
56286 98 21
56287 46 22
