Did some light steering in the 3C vertical line to take harp swipes, was having issues with harp fitter tool giving us a fit with 3 peaks. Ben also changed the lock positions and set them back afterwards.

Body: Fopt 7.9 completed successfully. The runtime settings include a sample count of 15, a minimum current of 4, and an operating regime of Standard with Excitation in 1S Region. The corrector and RF kicks applied were 0.488208 and 0.488208 volts respectively. The max. amplitude setting was 1 millimeters. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/26apr132009. The X and Y stability of the machine during the run was 0.0663636 and 0.0481953 (mm) respectively.

Compared the machine "design" optics to the optics at present in the machine in figs. 1 and 2 courtesy of D. Turner who provided the data logger snapshot file of magnet/rf settings and elegant .ele and .lte files. One sees a substantial difference with the beta functions and dispersion in both planes growing substantially by the end of the 2nd pass through the linacs. So, not surprising any motion at the injection end of the machine gets amplified as the beam is accelerated. Note the large difference in scale between the two figures.
