Purpose

This code generates histograms based on the PCL-Alignment for the SIPixel large structures. The histograms can be accessed via a web page. This web page is updated each morning to add the runs of the last day.

Code

makePlots.py is the main script, which is executed while updating the webpage. The following main tasks are fulfilled running this script:

• Dowload of root files containing the PCL-Alignment for each run:

  • For this step the downloadViaJson.py script is used.
  • After enabling the Grid-Certificate the newest dataset for a given pattern, e.g. /StreamExpress/Run2018*-PromptCalibProdSiPixelAli-Express-v*/ALCAPROMPT, is searched. This pattern has to be manually adapted when changing to a new year or HI runs.
  • The root files for runs not already present in the root-files folder are downloaded from dqm.
  • A list of new runs is returned to the main script.

• Plot nominal histograms:

  • For each run not already plotted in eos/project/c/cmsweb/www/pixAlignSurv/plots a histogram for each of the six parameters is plotted based on the root file downloaded before.
  • Each plots consist of the first 6 bins of the histograms present in the root files, which correspond to the different large structures.
  • In case one of the entries exceeds a cut value, which are manually set at the top of makePlots.py, a mail is sent to the alignment conveners

• Plot alignment VS runNr:

  • For each parameter the alignement is plotted against the runNr, taken from the name of the root file.
  • Vertical lines for new algments given by tags like SiPixelLorentzAngle_fromAlignment_v1_hlt can be added.

• Plot alignment VS time:

  • If available the time stamp present in runTime.pkl is assigned to the corresponding run.
  • In case of a missing time stamp or new runs this time stamp is taken from conddb using conddb listRuns.

• Update web page:

  • The html file is based on the structure available in indexTemplate.html.
  • The time is updated with the current time stamp.
  • For each run the runNr, EndTime and the corresponding alignment plot for the six parameters are shown.
  • In case the first 6 bins in a root file are empty, "no result" is displayed.

To run this code on a daily base the acronExe.sh script has to be added to the own crontab as decribed at the top of this bash script.

Adaptions to run the code

• The paths present in acronExe.sh have to be adapted
• Change access rights (write/read) for the eos directory eos/project/c/cmsweb/www/pixAlignSurv/plots
