105Operating the Beam Profiler
In the case of a focussed beam, the hyperbolic data fit is recommended. In addition
to this fit selection the program is able to identify a coarse beam gradient. If the M²
measurement is chosen but the beam shows a linear slope with a beam width
variation of less than 50% the Beam software will suggest a linear fit.
If the program detects a (unfocussed) linear beam propagation instead of a
(focussed) hyperbolic one the software will recommend to proceed with Divergence
measurement perform a linear fit to the data points.
