filename
-- Name of SDDS file from which to take data. The file
must contain some of the following columns:
change_defined_values
is set, successive pages of the file are used for
successive steps of the simulation. Several elegant commands generate output that
may be used (on a subsequent run) with load_parameters
; among these are
the tune and chromaticity correction commands and the run_setup
command (parameters output).
change_defined_values
-- Changes the defined values of the parameters.
This means that when the lattice is saved (using save_lattice
), the parameters will
have the altered values. Also, if you want to alter the values for all steps of the
simulation, you must set this flag.
clear_settings
-- If set, clear all settings and files being used for loading parameters.
allow_missing_elements
-- If set, allow elements in the file that are not in
the lattice. In this case, the nonapplicable data is simply ignored.
verbose
-- If set, provide informational printouts about changes to parameters.
