Hi John,

The algo changes are committed so you can re-download and test. In settings the there is a new 'model' field, this takes a number 0->4 inclusive.

0: Old global gaussian fit,
1: Simple global energy maxima
2. New global parabolic fit
3: Local energy maxima then gaussian fit around this maxima
4: Local energy maxima then parabolic fit around this maxima

For laser the best is 4, please let me know for the wire, you may find that since the wire shadow is much less noisy and narrower than the laser that the original model works best still. Also note I have increased the default smoothing (settings->smoothingFactor from 3 to 20), you may want to reduce this for the wire shadow as it is narrower.
