Focus Position

The Focus position can be analysed from a series of measurements. In this subversion the list of supported devices for structured multiple data sets is accessible in the user interface.

A sigmoid analysis is used to find the center of each profile. This is much more stable for 2D arrays. Although the sigmoid point deviates from the classic 50% position, the average of left and right edge will give the correct result. In the graph below only the right border values are shown.
