Fix or understand grid requirements
- we are getting the exception
Exception: define_limit_grid could not detect combined datacard variables COMBCARDS,COMBCARDS_POINTS,COMBCARDS_VBF,COMBCARDS_VBF_POINTS
While only COMBCARDS is defined in setup
If that is commented we get the following
Exception: define_limit_grid encountered unstable limit interpolation with grid_min (-0.00987420952879) >= grid_max (-0.0618157023564)
Something should be added in this setup, or something should be ran before launching the grid?
