+When we open the NUISANCE output file in ROOT we can see that it contains a series of histograms all with names similar to the sample names we specified in our card file. By default NUISANCE preppends the name of the sample to any histogram when writing it so that you know from what sample each histogram originated from. 
+
+Lets go through some of the histograms of interest.
+
+- ** MiniBooNE_CC1pip_XSec_1DTpi_nu_data ** : This is the data histogram we are trying to compare to for the Tpi distribution. Drawing this with the ROOT draw option 'E1' will draw us the error bands.

+
+- ** MiniBooNE_CC1pip_XSec_1DTpi_nu_MC ** : This is the MC histogram for our model binned in exactly the same binning as the data. This histogram is used to calculate a likelihood by directly comparing to the data. By default the title of the MC histogram is also set to the value of the likelihood for easy reference. In the plot below the chi2 was calculated to be : 25.749
