- Twiss output contains entries for the higher-order dispersion, tune shifts with amplitude, higher-order chromaticity, tune spreads
due to chromaticity and amplitude, and resonance driving terms even when these are not calculated, which is potentially
misleading. The values are zero when the calculation is not requested.
- Computation of closed orbits and Twiss parameters will not always include the effects of synchrotron
radiation losses when these are imposed using SREFFECTS elements. See
the documentation for SREFFECTS for details.
- Computation of beam moments does not include synchrotron radiation effects from
CWIGGLER,
WIGGLER, or UKICKMAP elements.
- The file created with the parameters field of
run_setup does not contain
any non-numerical parameters of the lattice.
- When
transmute_elements is used to turn a sextupole into a quadrupole, several problems are seen.
Some of the quadrupole parameters are filled with garbage values. When alter_elements or
save_lattice are subsequently used, elegant crashes. These problems were reported by
V. Sajaev (ANL).
