Noise run analysis

1. General Information

RUN Trigger Sequence Trigger Mode Frequency Events
53536 L2a RANDOM 4 KHz 1645
53522 L2a BC 40 Hz 1093

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
53536 1571 1099
53522 255 231
