The centroid and sigma output from run_setup is not correct when BRANCH elements are
used.
The REFERENCE_CORRECTION feature of the CSBEND element is ignored while performing
calculations related to the moments_output command.
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 whenthese 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.
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
The OUTPUT_FILE feature of the TFBDRIVER will produce a file with missing data at the
end of the buffer if the OUTPUT_INTERVAL parameter is not a divisor of the number of
passes.
When the KQUAD element is split (with the divide_elements command or element_divisions),
edge multipoles and the LEFFECTIVE feature cannot be used.
