• response -- Array of (incomplete) filenames for SDDS output of the x and y response matrices. Recommnended values: ``
• inverse -- Array of (incomplete) filenames for SDDS output of the x and y inverse response matrices. Recommnended values: ``
• KnL_units -- Flag that, if set, indicates use of ``units'' of m/K0L rather than m/rad. This results in a sign change for the horizontal data.
• BnL_units -- Flag that, if set, indicates use of ``units'' of m/(T*m) rather than m/rad. This is useful for linac work in that the responses are automatically scaled with beam momentum.
• output_at_each_step -- Flag that, if set, specifies output of the data at each simulation step. By default, the data is output immediately for the defined lattice.
• output_before_tune_correction -- Flag that, if set, specifies that when output_at_each_step is set, that output shall occur prior to correcting the tunes.
• fixed_length -- Flag that, if set, specifies output of the fixed-path-length matrix.
