output
-- The (incomplete) name of an SDDS file to send output to.
Recommended value: ``%s.fma''. For the parallel version, particles will be listed in essentially
random order. If needed, sddssort
can be used to sort particles by initial coordinates.
xmin
, xmax
-- Limits of grid of initial x coordinates for tracking.
ymin
, ymax
-- Limits of grid of initial y coordinates for tracking.
ymin
should typically be a small, positive value so that there
is some betatron oscillation from which to get the tune.
delta_min
, delta_max
-- Limits of grid of initial coordinates
for tracking. Not that particles are not centered around the dispersive closed orbit. Hence,
the tracking is appropriate to simulation of dynamics from a touschek scattering event.
nx
-- Number of values of x coordinate in the grid.
ny
-- Number of values of y coordinate in the grid.
ndelta
-- Number of values of coordinate in the grid.
verbosity
-- If nonzero, prints possibly useful information while running.
include_changes
-- If nonzero, then computes not only the tunes, but also
the changes in the tunes. This is expressed in terms of the diffusion, which is defined
as
