-> Select spacing/number of settings(points)
7

8

9

10
	- when exit the step menu the corrector is restored to original setting.
11
-> Fit the TBT data taken, cycle through all steps
12
-> Fit phase/strength 
13
	- The two resulting parameters are stored in a calibration data record
14
-> Plot data(fitted phase/amplitude)
15
	- A bull's eye plot show data quality.
