cta_2085mev_xr20m_20091205.lat With Quad Errors

Summary: Start with XR20m lattice and add errors at the following levels:

Note: these values come from the most recent survey data. Generate errors in ring_ma and simulate correction using a 2-stage technique:

Horizontal steerings aren't necessary, because the horizontal orbit is not perturbed significantly using these misalignment parameters. Apply these errors at 1/10, 1/2, and full values.

Run a tune scan on each resulting lattice from 0.5-0.666 in 0.002 steps. Plot the resulting data using a Python plotting script to ensure all scales are equivalent.
