SSD DDLs 16
SSD LDCs 3
Duration 08:31:13

The overall information for this run can be found here.

The number of the SPD FastOR triggered events and the total number of golden clusters per layer are seen below:

FastOR Events Layer 5 Layer 6
2937 6869 6017

2. OCDB files

The OCDB files that were used for the reconstruction of this run were produced by the SSD DA during the pedestal run with the number 61909. The plots below show the map of the bad channels:

3. Analysis of clusters

Here are some histograms obtained with the official offline QA for the SSD clusters. In all plots we see the accumulated statistics from all the events of this run. There was a selection on the golden clusters.

4. L0 timing adjustment

These are the distributions of the cluster charge grouped by DDL for the run where the timing was set to CB. To convert the moduleID to DDL I used a modified AliITSRawStreamSSD class by adding the GetDDLFromModuleId. The distributions were fitted with a Landau (red curve) and the results of each fit can be seen in the statistics box. For the cases where the fit was practically useless, we don't show it (low statistics - side half ladders).
