Actually, I did implement an option to change the normalization. The syntax of the branch is:
where <f> is a multiplier applied to the normalization defined using the "set power", "set powdens", etc. cards. I'm not 100% sure that this works with equilibrium xenon calculation, though, because I came up with the idea of switching the calculation off using the "xenon" and "samarium" branches before testing the method.
Could you give it a try and let me know if it works?
