You can study this the geometry of FCChh-v4 detector using sifcch4 link. This geometry corresponds to rfull006 tag SLCIO files.

We will download samples in directories dataNgev using reg. expressions. We will use 2 threads and 100 files (if available) from each sample.

hs-get pgun_pi_1to10000gev%rfull006 data1gev 2 100 pi1gev         # 1 GeV sample
hs-get pgun_pi_1to10000gev%rfull006 data10gev 2 100 pi10gev       # 10 GeV sample
hs-get pgun_pi_1to10000gev%rfull006 data100gev 2 100 pi100gev     # 100 GeV sample
hs-get pgun_pi_1to10000gev%rfull006 data1000gev 2 100 pi1000gev   # 1000 GeV sample
hs-get pgun_pi_1to10000gev%rfull006 data10000gev 2 100 pi10000gev # 10000 GeV sample

Run a Python script given here: pgun1.py. To process these samples, run this sequence. Each scripts creates a PDF file with the image.
