Hello Christoph,

according the residuals I found on Wikipedia that in general it means "distance of a measured point to the function", in our case the track. In the name residual it is not determined how the function is defined.

I propose to explicitly state which residuals we refer to:

  • r_n : residual with all hits in the track fit
  • r_(n-1) : residual with the test hit excluded in track fit
  • r_geo : geometric mean of r_n and r_(n-1)
  • r_MC : residual to Monte Carlo truth as track
  • r_hod : residual to track from hodoscope


Cheers

Martin
