This wiki outlines some potential usages for NUISANCE.

If you haven't yet build the framework, do so [https://nuisance.hepforge.org/nuisanceinstallation.html 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.
