<p>A linear function was fitted to the reference point channel (from experimental histogram) and reference point energy (from simulation histogram). The reference point&nbsp;&#39;r&#39;&nbsp;was r=mean+(FWHM/2) for a gaussian fitted to each compton edge.&nbsp;</p>

<p>The comparrisons between the calibrated experimental and simulation histograms has been attached. P1 (left) and P2 (right) on the Y88 hisograms indicate whether the histograms were scaled with respect to the leftmost or rightmost compton edge (only to allow easier comparrison).&nbsp;</p>
