Note how peak locations seem to fall in a grid like pattern. This is to be expected when you are capturing every 4th pixel.

3.2.9.3.3Real World Units

Setting LBA-PC’s Quantitative results to real world units of length such as µm and mm may be accomplished by going to the main menu and choosing:

Option > Camera

Make the appropriate real world unit selection in the Pixel Units drop down box. This method of analyzing beam stability is in many ways similar to that discussed above however when viewing the scatter plots the user must understand that the X/Y-axes will be in whatever units are selected above. Also, the grid lines of the scatter plots will not have the same granularity as the pixel grid on the detector. This method is best when scientific units of length or beam centroid displacement are needed. When one understands the method explained above this method should be intuitive. Remember to reset the scatter plot whenever units are changed in LBA-PC.
