Command Line Interface (CLI)

Io order to facilitate the usage of the code, we provide frontend command-line interfaces that help the user access the main functionalities.

Produce interpolation tables

The pyhton program tables.py produces fast interpolation tables according to the parameters set by the user.

Prepare and run a fit

The python program fit.py prepares and runs a fit. The results of the fit will be put in a new folder created by fit.py itself with a name chosen from the user. Answering the questions asked by the command line interface the user can choose:

  • the experiments to include in the fit (among the avaliable ones),
  • the perturbative level to which the calculations in the fit will be carried (and consequently the convolution tables associated with it),
  • the minimiser to use (none gives only predictions, and the other two avaliable choices are minuit and ceres),
  • the random-number seed for the generation of the Monte-Carlo replicas,
  • the maximum value qT / Q allowed in the fit,
  • the cut on the value of the error function (used for the report),
  • if to use or not the t0 prescription and with which parameters,
  • the parameterisation for the non-perturbative function (among those that are avaliable) and the initial parameters,
  • if to fluctuate or not the initial parameters,
  • the number of Monte-Carlo replicas.

Produce a report of a fit

The pyhton program report.py produces a report starting form the output folder of the fit.
