Yes. The conclusion I've come to is that the inner slit determines
the overall shape of the image when it hits the film plane and the
outer slit determines distortion within this shape. There's a lot
going on beyond this simple rule, but using it has helped me better
match slits with subject.

15 #1 : "These are apparently caused by the light rays / waves with
form the two separate images becoming out of phase with one another."
