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 49962. 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.

5. Global QA

Below you can find the residuals for both SSD layers calculated within the Global QA. The results in the statistics' box come from a Gaussian fit which is not drawn.
