Lets say that we have a two fits that we are trying to implement. I will assume that you have this version of double gaussian and exp class.

You really should use this one instead. It includes more sanity checks and allows you to pass iminuit limits as optional. This means that you don't have to always put (-np.inf, np.inf) for each limit anymore.

class DoubleGaussian_plus_Exp:
    def __init__(self, bins, nC, minuit_limits=None):
        self.xMin, self.xMax, self.bin_width, self.x_vals, self.y_vals, self.y_errs = self.Fit_Setup(nC, bins)

Both are designed to integrate changes from one branch into another; however, they do this in very different manners and with different end results

Merge

The merge command is a way to take the contents of one branch and integrate them into another. It does this by creating a new commit that incorporates changes from other commits.

When we issue a git merge, Git will create a new commit that has pointers to both the branches we're merging. This is referred to as a merge commit, and it is a clear way to see when a file history was altered due to a merge.
