Results from the run 44045

1. General Information

RUN 44045
Events 1203
Detectors SPD - SSD
SSD DDLs 16
SSD LDCs 3
Duration 03:54:19

The overall information for this run can be found here.

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 44022. The plots below show the map of the bad channels:

The gain calibration file used was the proper one, but still from the LHC08b period of the machine (the AliEn OCDB was not synchronized with the DAQ logbook).

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. Visualization

For the reconstruction of these data, we used v4-13-Release and the official AliEn OCDB entries.

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.
