Alex wasn't kidding when he said these scans take forever.
Once again when we powered up all the programs and equipment, the detector wasn't picking up anything. We checked the calibration with the Fe-55 and the gain was extremely off. We restarted the computer and everything was in working order again. To fix the astigmatism we had to move the z of the source in the positive direction. Alex suggested going by 2mm intervals and then graphing all the data to see which OFD minimized the astigmatism. The scans were run at 1.0 second preset time. We were only able to complete a full y and partial x scans at 202mm before lunch. When Dr. McColgan came with me after lunch, the x scan was completed along with a full y scan at 204mm.
