This ROOT script will plot the residual and pull of perigee track parameters (d0, z0, phi, theta, q/p, pT, t) from root file produced by the RootTrajectorySummaryWriter

Parameters

inFiles	the list of input files
inTree	the name of the input tree
outFile	the name of the output file
inConfig	the (optional) input configuration JSON file
outConfig	the (optional) output configuration JSON file
residualPulls	the bitset of the parameters set

Note

A lot of this could be done with creating appropriate TH3F histograms and chose the relevant projections, but this would need one loop through the entries per parameter and would create a very long analysis turn-around. That's why the data/histograms are prepared in handles and then filled in a single event analysis loop.

Helper method to handle range without possibility to read in

Parameters

handle	the parameter handle in question
handleTag	the unique tangle tag
peakEntries	the number of entries used for range peaking

Preparation of handles / acceptance range

Helper method to analyse bins

Parameters

residualPullsMatrix	the 2D matrix of handles
auxiliaryMatrix	the 2D matrix of the auxiliary handles
matrixTag	the identification tag for the matrix
outputBorders	the border vector for the outer bins
innerBorders	the border vector for the inner bins
fXTitle	the title of the x axis of the first projection
sXTitle	the title of the x axis of the second projection

Note

this is a void function

Write out the projection histogram

Parameters

h2	the 2D histogram as source for the projects
fXTitle	the title of the x axis of the first projection
fYTitle	the title of the y axis of the first projection
sXTitle	the title of the x axis of the second projection
sYTitle	the title of the y axis of the second projection
