Usage Examples

This wiki outlines some potential usages for NUISANCE.

If you haven't yet build the framework, do so ​here.

The card file

NUISANCE requires the user providing an input card file which species:

• The data sample(s) to compare to
• The generators and their file locations
• Any additional parameters that a sample might take (optional)
• A normalisation factor to apply uniformly to the MC (optional)

When the generator provides a reweighting interface, systematic parameters to reweight or fit can be provided. To do this we need:

• Name of the systematic parameter in the reweighting engine
• Current value of the parameter
• Minimum value of the parameter (optional)
• Maximum value of the parameter (optional)
• Starting value of the parameter (optional)
• Whether we FIX or FREE the parameter

All NUISANCE executables run based on the card file, except for when producing generator flat trees.
