Detailed Description

Utility class to allow the merging of data files on a expt-by-expt basis.

Utility class to allow the extraction of the best fit from a series of fits to a given data sample.

The files are merged such that events for expt 0 from tree 1 will be followed by events for expt 0 from tree 2, then expt 1 from tree1, expt 1 from tree 2, etc.

A utility class to allow the extraction of the best fit from a series of fits to a given data sample.

When fitting amplitude models, the likelihood parameter space is highly complex. Hence the fitter can often wander into local minima. To mitigate this effect a data sample can be fitted many times with randomised starting values of the isobar parameters. It is then necessary to determine which of these fits gives the best solution, i.e. the minimum NLL. This class performs this task, reading in a series of fits for each data sample and writing out a single file that contains the results of the best fit for each data sample.
