def plotCentroidsTrace(self,pointsPerBin=10):
        """
        Plot all centroid positions for a particular aperture radius,
        for each comparison star. The plot will be in (`x`,`y`) coordinates
        to visualize the physical image drift (this is not a plot as a function
        of time).

        Parameters
        ----------
        pointsPerBin : int, optional (default=10)
            Integer number of points to accumulate per bin.

        apertureRadiusIndex : int, optional (default=0)
            Index of the aperture radius list corresponding to the aperture radius
            from which to produce the plot.
