The resulting radius of curvature is R = 2701.0822 mm with RMS = 0.2431 mm.<br></div><div><br data-mce-bogus="1"></div><div>The program also plots the CMM data and then uses the calculated radius and sphere center point to draw the sphere the mirrors have been cut from. Plot is shown in the attached image.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Best regards,<br data-mce-bogus="1"></div><div>Tyler<br data-mce-bogus="1"></div></div></body></html>
