+ | You can also look at timing of silicon tracker using this script: {{: | ||
+ | <code bash> | ||
+ | hs-get pgun_elec_eta4_pt30gev%rfull052 data # 2 100 get 100 files in 2 threads in the directory " | ||
+ | fpad eic: | ||
+ | </ | ||
+ | The plot is shown here: | ||

+ | |||
+ | ====== Looking at track resolution ====== | ||
+ | |||
+ | You can also look at single particles with flat pT, Eta and Phi. Here is an example this using a simple validation script {{: | ||
+ | for the MCparticle container inside LCIO file. We will use the "flat pT" sample called [[http:// | ||
+ | |||
+ | <code bash> | ||
+ | hs-get pgun_elec_eta4_pt30gev%rfull052 data 2 100 # get 100 files in 2 threads in the directory " | ||
+ | fpad mc_truth_flat.py | ||
+ | </ | ||
+ | |||
+ | The resulting image is: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Now, let's calculate track resolution. We will use this script {{: | ||
+ | makes fit of pT(reco)/ | ||
+ | This command shown below makes resolution plots, fits with a Gaussian function, and plot resolution as a function of pT: | ||
+ | <code bash> | ||
+ | hs-get pgun_elec_eta4_pt30gev%rfull052 data 2 20 # get 20 files in 2 threads in the directory " | ||
+ | fpad track_resolution.py | ||
+ | </ | ||

+ | The final plot is shown below: | ||
