prof2-tune ========== .. note:: This script requires :code:`iminuit` to be installed. Run minimisation of a goodness-of-fit measure of the parametrisation and data. :: prof2-tune DATADIR IPOLFILE --wfile WEIGHTFILE Options: :: --limits LIMITFILE # Specify a text file to fix parameters to certain values or force the parameter to be in certain bounds --scan NPOINTS # Scan a grid of NPOINTS^P points to look for a good starting point (by default the centre of the parameter space is used) -s STRATEGY # Set Minuit strategy Weight syntax _____________ Weigts are used to enhance the importance of observables or bins in the goodness-of-fit measure. The weight for a range of bins of a histogram can be specified wither depending on the value of the observable (bin edges) using :code:`@` or the directly specifying the bin index using :code:`#`. A few examples: :: /ATLAS_2010_S8918562/d03-x01-y01 1 # Set weight to 1 for each bin of this histo /ATLAS_2010_S8918562/d05-x01-y01 100 # Set weight to 100 for each bin of this histo /ATLAS_2010_S8918562/d07-x01-y01@0:20 10 # Set weight to 10 for bins with binEDGES in [0,20) /ATLAS_2010_S8918562/d07-x01-y01@20:40 50 # Set weight to 10 for bins with binEDGES in [20,50) /TOTEM_2012_I1115294/d01-x01-y01#0:20 10 # Set weight to 10 for bins with binINCIDES in [0,20) /TOTEM_2012_I1115294/d01-x01-y01#20:40 50 # Set weight to 10 for bins with binINDICES in [20,50) Limits syntax _____________ * Simple text file * Parameter name followed by one number is interpreted as fixing the parameter to that value * Parameter name followed by two numbers is interpreted as imposing bounds on the parameter Example: .. raw:: html
