Using the perl/PDL script, beam sizes for Y (quad scan 0) and X (quad scan 1) were measured. These beam sizes were put into a "sdds" file so the nominal CEBAF emittance/TWISS tool could be used to plot and fit the data.
Two fits are performed a simple Least Squares Fit and one based on MINUIT. The LSF is also used to seed the MINUIT fit.
Y plot and the GUI with results for the first quad scan.
