- Setting
`CHANGE_T=1`

on`RFCA`

and`RFCW`

elements can give invalid results when tracking beams with very large time spread compared to the bunch length. - Twiss output contains entries for the higher-order dispersion, tune shifts with amplitude, higher-order chromaticity, and tune spreads
due to chromaticity and amplitude
*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
`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). - Computation of radiation integrals does not include the effect of steering magnets.
- There is a bug related to using
`ILMATRIX`that will result in a crash if one does not request computation of the twiss parameters. If you encounter this problem, just add the following statement after the`run_setup`

command:&twiss_output matched = 1 &end
