I don’t think I have the alignment instructions beyond what’s posted on my blog. You just set one parameter to 1, which gets you pixel values, and there’s a solver included that, given a bunch of pixel and wavelength relationships, solves for the rest.
It’s been a while since I’ve done it, but everything you need should be there.
