Higher order dispersion

Hi Michael,

In the twi file elegant outputs etax2 and etax3 at the starting point only. Elegant must have calculated these quantities internally at every point. Is it possible to output the values at the fitpoints?
I could obtain these functions from the off-momentum closed-orbit, but it would be a much faster optimization if elegant does it directly. Or, do you have a way to generate it in the twi file?

Thanks,
Weiming

Weiming,

Actually, elegant only computes those at the start/end of the lattice, but does have the data internally to do it everywhere. I'll add it to the list of things to do.
