momentum aperture

Hi Michael,

When I used momentum_aperture for one nsls2 supercell, I expected to see some fluctuations along the ring, such as small aperture at dispersive section. But I get almost two parallel lines as shown here:

.

I attached both ele and lte files. Do me a favor to take a look at them whenever you are free, please.

command line:
elegant LMA.ele -macro=fn=nsls2cell.mmap,s0=0.0,s1=52.7972

Regards,

Michael,

We found the problem: it was the RF voltage is too low. Anyway, thanks.
