Offline monitor analysis

IDEA: analysis of a sample of reconstructed events (a step forward after the check made by the online monitor), in a short time, just after the run is finished

How to implement it ?Status of the workQuestions? Suggestions?

CU Beamtest Workshop III, June 28-30, 2006C. Cecchi – S. Germani – M. Pepe

How many events with the reconstruction?

-it depends on the time between runs (?)

Start from xxx_digi.rootxxx_merit.rootxxx_recon.rootxxx_svac.root

Complete reconstruction of a sample of events is nedeed:- Tracks: number, directions- Cal: energy, directions- Acd: energy- Trigger- Ancillary: positions, directions

Code is now running under root as a simple macro for the user Do we want a compiled versions? Yes.... Add it to the pipeline.

- Open and read output files from Gleam (merit, digi)- Open and read a file with reference histo (available before the TB and based on MC simulation of different configurations )

- Select type of run: run number

beam energybeam angleparticle idmagnetic field

- Plot selected quantities- Make a comparison with reference histo - Produce warnings and/or alarms in case of failure

It would be possible to have thoseinformation in the file name ofthe data?

List of selected variables (II):

Trigger (from Digi): - GemCondSummWord (temp from Merit) - GemCondArrTime (not filled in MC)

Acd: - AcdTotalEnergy - AcdTileCount

Ancillary (Z=beam axis!) : - positiony[i=0,3] vs positionz[i=0,3]

The code is available and running (an example can be shown during this workshop if people are interested)

All possible changes can be discussed here and implemented before the TB

Reference histos for all the configurations to be produced

Comments/suggestions are welcome!

Where we are?
