Navigation:  Special computations > Function fluctuation

This object type is even more flexible than the Optical function fluctuation type described above. The x- and y-coordinates of the displayed points are computed according to user-defined functions. These may refer to values of objects in the list of optical functions (the term of(4) takes the 4th object in the list of optical functions) or objects in the list of integral quantities. The latter is available in the CODE software only (not in SCOUT!). You can refer to integral quantities by iq(xx) where xx denotes the position of the wanted object in the list. The term iq(23) takes the value of the 23rd integral quantity.

Since terms like of(5)-iq(12) refer to absolute positions of the wanted objects in their lists, you must not change the order of the optical function objects or integral quantities. If you did so, you should check if the expressions do still what you intend.

 

An example for a Function fluctuation object is given below:
