# Database:
# - replace the name and location of the local DB before running!
# - payloads are searched for in the reverse order of DB's given below;
#   therefore the new calibration, if provided, is taken from the local DB.
# - one can even use several local DB's
b2.use_central_database('data_reprocessing_proc7')  # global tag used in production of cdst
b2.use_local_database('localDB/localDB.txt', 'localDB/')  # new calibration
 
# Create path
