This page is meant to document histograms in the standard Brunel output that are useful for detector alignment monitoring. For now, just add for the most important histograms a path in the root file.

Velo

  • /Velo/VeloTrackMonitor/m_prof_res_XX= shows the profile histogram of the residual versus the azimuthal angle for each sensor XX.
  • the script alignOfflineMoni.py (in Quality/MoniGUI/python) fits each histogram by a sinusoidal to evaluate the misalignment of each sensor. Two overview histograms summarize the misalignment results: the first histogram the results for the sensor with a misalignment above a warning threshold and the second histogram shows the significance of the misalignment for all the sensor.

TT

  • /Track/TTTrackMonitor/Ttrack/XXX/unbiasedResSector (XXX = TTaX, TTaU, TTbV, TTbX) shoes the unbiased residual versus sector. This plot is produced in fullDetail mode

IT

  • /Track/ITTrackMonitor/Ttrack/XXX/unbiasedResSector (XXX = ASide, CSide, Top, Bottom, Mixed) shoes the unbiased residual versus sector. This plot is produced in fullDetail mode

OT

  • /OT/OTTrackMonitor/respullvsmodule shows the average residual versus the module number in the OT.

MUON

Rich

  • /RICH/RichAlignMoniR1/dThetavphiRecAll & RICH/RichAlignMoniR2/dThetavphiRecAll show the distribution of Cherenkov angle with ring angle globally for RICH1 and RICH2. Sinusoidal deviations are expected with misalignment w.r.t. Tracking. For an aligned RICH, the amplitudes of these deviations will be <1 mrad.
