This is a plan agreed between ANL (Sergei Chekanov) and IHEP (Manqi Ruan). The document is observableproposed.docx

Setup analysis environment:

wget http://atlaswww.hep.anl.gov/asc/jas4pp/download/current.php -O jas4pp.tgz
tar -zvxf jas4pp.tgz
cd jas4pp
source ./setup.sh # takes 5 sec for first-time optimization

We will study single-particle files posted to as shown here. Let's check file availability:

hs-ls pgun_electron_eta3_pt150gev 

We will use the reconstruction tag “rfull101” which corresponds to SiCEPC detector.

Now download the files and calculate track resolution for electrons.

hs-get electron_eta3_pt150gev%rfull101 data/electrons  2 100 # get 100 files in 2 threads in the directory "data"
fpad track_resolution.py
