center_on_orbit
-- A flag indicating whether to center
the beam transverse coordinates on the closed orbit before tracking.
center_momentum_also
-- A flag indicating whether to
center the momentum coordinate also.
soft_failure
-- If there is an error during tracking (e.g.,
a failure of orbit correction), continue to produce file output. This
creates essentially empty slots in the files corresponding to the failed
steps.
use_linear_chromatic_matrix
-- For each particle, a first-order
matrix is computed for the particular momentum offset
of the particle using the linear chromaticity and linear dependence of
the beta functions on momentum.
longitudinal_ring_only
-- Tracks longitudinal coordinates only
for a ring.
