This example package serves several purposes:

• It illustrates how to initialize and access the detector description and magnetic field.

• It checks that the expected number of detector elements are created.

• It generates a set of neutral alignment constants for the Tracker, which can be folded into the conditions database.

• It dumps a standalone GeoModel sqlite geometry database which could be used by external programs to display FASER without requiring any FASER software (only GeoModel)

To run the algorithm, in a run directory where Calypso has been installed (displayed below as the command-line prompt run >), do

run > source ./setup.sh
run > python python/GeoModelTest/GeoModelTestConfig.py

The file GeoModelTestConfig.py can be edited to change some run options.

After running the algorithm, to add the alignment data into your local conditions DB, do:

run > CopyAlignFolder.sh
