Re-optimize sextupoles at new proposed working point of (0.625,0.542). Re-run frequency map, tune scan jobs. Compare to Frequency map, tune scan jobs at the same working point using original optimized (from 2010.05.04) sextupoles.

Try two optimization techniques:

• At new working point, start with 2fam distribution and optimize using same weights as for 2010.05.04 distribution
• At new working point, start with 2010.05.04 distribution and optimize using same weights.

Original Optimized Sextupoles, New Working Point

Use sextupoles optimized at original working point (0.571, 0.628), and run frequency map with working point (0.625, 0.542).

Starting with 2fam sextupoles

At new working point (0.625,0.542), start with 2fam sextupole distribution and optimize using original BMADz constraints.

Starting with 2010.05.04 optimized sextupoles

At new working point (0.625,0.542), start with sextupoles optimized on 2010.05.04 for original working point (0.571, 0.628). Optimize using the same BMADz constraints.
