	Bragg diffraction in the presence of a high numerical aperture focusing optic results in complex images created by a range of incident beam angles. These images can in certain cases be understood through a tilt series either imaging a broadened diffraction peak in a reciprocal space map or directly extracting the 1-D diffraction pattern directly from the far-field diffraction data. These demonstration scripts are loaded in the user Analysis directory and can be looked at with ctr_demo.m <br />		Bragg diffraction in the presence of a high numerical aperture focusing optic results in complex images created by a range of incident beam angles.

 iii) When focusing on a round object 2D maps may be necessary at several focusZ positions, this can be done manually or with the panelfocus() command <br />
 iv) Typical signs of being out of focus are large centroid motions near object edges (L/R up/down), and sharp objects showing up as a series of donuts in a 2D map <br />
