It will download all of the beampackage code for the first time use and will guide you how to set your environment file. Also you can download the beampackage by hand from [http://hallaweb.jlab.org/experiment/g2p/collaborators/pzhu/wiki here].

Introduction

calibration code

A new beampackage python script is built for bpm calibration, you can check the detail from here.

To use it, just simply type:

./bpm.py rootfilepath (if it is not absolute path you need to define the rootfile path in the bpm.py file)

or:

./bpm.py runnumber (this way will insert all of the rootfiles for this run and you need to define the rootfile path in the code)

That's it!
