As of the latest survey measurements, the quad tilts in the actual machine have a sigma of ~220 micro-radians. Introduce quad tilts with this sigma for both 2fam and optimized sextupole distributions, and run tune scans over the half- to 2/3-integer domain.
Compare to tune scans from ideal lattice with 2fam sextupoles.
Compare to tune scans from ideal lattice with optimized sextupoles. Note that the tune scans performed during machine studies covered the region ~[0.538,0.565]x[0.577,0.655]. See elog entry here.
