VELO Online Monitoring Wish List

This page is meant to be a scratch area for collecting ideas what to monitor and how. So everybody should feel free to add
Line: 55 to 55
 
  • residuals (preferably for small angle tracks with many spacepoints)
    • vs r/phi for alignment
      • for each sensor make unbiased straight line track fit and compute intercept with sensor

      • calculate residual (DeVeloSensor)
 
      • for R sensor: plot residual vs phi (calculating phi from track state)
      • for Phi sensor: plot residual vs r (calculating r from track state) and vs phi (phi of strip at minimum strip radius +/- stereo angle)
Changed:

      • update frequency: order of 10 seconds
      • when histogram has about 10'000 entries at least 1 minute old) create a ProfileX() (root method)
      • this profile should be kept, update can be ensured to be >=1min
      • fit profile with sin+cos+const

      • update frequency for residual scatter plots: order of 10 seconds
      • when histogram has about 10'000 entries at least 1 minute old) create a ProfileX() (root method)
      • this profile should be kept, update can be ensured to be >=1min
      • fit profile vs phi with par_0 * sin(phi) + par_1 * cos(phi) + par_2
        • plot distribution of par_0 and par_1 for all sensors in one histogram
        • this will be an overview histogram of x/y misalignments, update frequency same as profile: >=1min
      • fit profile vs r with par_0 * r + par_1
        • plot distribution of par_0 for all sensors in one histogram
        • this will be an overview histogram of z-rotation misalignments, update frequency same as profile: >=1min
 
      • (all code available from software alignment)

Quantities derived from NZS Data
Line: 83 to 90
 
Higher level quantities
  • tracks (this is very generic, needs to be fleshed out, like e.g. below)
  • residuals (preferably for small angle tracks with many spacepoints)
Deleted:
<

    • vs r/phi for alignment
 
    • vs beetle readout direction for R sensor x-talk
    • vs pitch and angle for resolution
    • (more or less all of this code already available in sensor alignment software)
Line: 98 to 104
 

Considered

  • beam position
