Improvements in the error calculation of the action of a kicked beam

This report details a new calculation for the action performed in the optics measurement and correction software. The action of a kicked beam is used to calculate the dynamic aperture and detuning with amplitude. The current method of calculation has a large uncertainty due to the use of all BPMs (including those near interaction points and ones which are malfunctioning) and the model beta function. Instead, only good BPMs are kept and the measured beta function from phase is used, and significant decreases are seen in the relative uncertainty of the action.
