Detailed Description

This systematic smears the momentum of tracks with TPC information, by a random amount from a Gaussian distribution.

The amount each track is changed by uses two Gaussian distributions. The first distribution uses the input parameters to select a resolution. This is called once for each virtual analysis. The second distribution then uses the chosen resolution as its width, and the amount to vary each track's momentum is chosen from this distribution. This is called for each track individually.

§ TPCTrackEffSystematics()

TPCTrackEffSystematics::TPCTrackEffSystematics ( bool  computecounters = false)

this is only 1 toy experiment, as we only store the weight for a change of one sigma. The mean and sigma for each momentum bin is defined in a data file. the Gaussian distribution from which the resolution of each virtual analysis is selected from.
