Is there a way to have it measure the width at the half height point
instead?
it searches for largest gradient (derivation) in given direction.
Thats also why step up and step down is a separate function.
If there is larger gradient in different part of your data
(e.g. due to noise), you can fix the position slightly selecting
only part of data to be fitted and omitting the wrong data,
but if there is noise close to step or on step, it cannot be
done in this way.

When using the critical dimension feature to measure step edges, how
does Gwyddion determine where the vertical edges are? How does it
determine where x1 and x2 should be?
