For conversion of electron dose images.
There are two parameters, a and b. y = (x - a) / b. The perameters default to 740.5 and -42.5, and they can be set with the parameters menu.
For example, here is a dose image, with the yellow rectangle to crop out some of the edges, which are funky, although you can't see that in this image.
This image is esem3 in the sample images folder of this widget.
