Matlab AT 2.5

Main changes

• A new keyword df is introduced to specify to specify off-momentum computation, in addition to dp and dct. It is available in atsetcavity, findorbit*, findm44, atlinopt*, tunechrom,

• Radiation tapering can be set using attapering. Tapering is based on a new attribute FieldScaling added to all magnet passmethods,

• A set of new "exact" integrators is introduced: ExactDriftPass, ExactMultipolePass, ExactSectorBendPass, ExactRectangularBendPass.

• The physical constants used in the C integrators have been updated to the CODATA 2018 values. The values used in python come form scipy.constants and were already up-to-date. So because of an update of the Cγ constant,

  results related to radiation and slightly different from the previous values.
