Hmm- looks like crosssec calculates F' and F" (and cros-section). I guess you're thinking of the "x-ray edge" page on the same server. Ive got local copies and graphs of that in an excel spreadsheet. I was thinking about the page where you enter your protein's molecular weight, number and type of anomalous scatterers, and it tells you how accurate your data has to be to make the anomalous signal significant.
