The reference point 'r' was r=mean+(FWHM/2) for a gaussian fitted to each compton edge. A quadratic function was used as it fitted the higher energy AmBe reference point better than a linear function. This is highlighted by the comparisson of "STED 2 Calibration" and "STED 2 Example Linear Fit Calibration" plots below. The p0 error is quite large and p2 error very large (larger than the parameter value in STED1) - however the parameters are highly correlated which may have inflated the error. </p> <p>CmC histograms were not used as the compton edge could not be located. </p> <p>For reference the STED 1 correlation matrix:</p> <table border="1" cellpadding="1" cellspacing="1" style="width:500px"> <tbody> <tr> <td> </td> <td>p0</td> <td>p1</td> <td>p2</td> </tr> <tr> <td>p0</td> <td>1</td> <td>-0.92473</td> <td>0.78779</td> </tr> <tr> <td>p1</td> <td>-0.92473</td> <td>1</td> <td> -0.91714</td> </tr> <tr> <td>p2</td> <td>0.78779</td> <td>-0.91714</td> <td>1</td> </tr> </tbody> </table> <p> </p>
