The new camview has features of Gaussian and super-Gaussian fit, demonstrate FWHM and 1/e2 width.
In "Show/hide", select "projection" then box 1, box 2, vertical, and horizonal lineout will appear.
box 1:
choose the crosshairs' position (2 in this case) to show lineouts
ROI Avg: this will show integral average over both directions
Auto range: this will automatically adjust the intensity range
Gaussian: Gaussian fit
Super Gaussian ( p=4): This is 4 order super Gaussian fit
Super Gaussian (p=6): This is 6 order super Gaussian fit
