INITIAL_V	$V$	double	0.0	initial voltage
INITIAL_PHASE	$RAD$	double	0.0	initial phase
INITIAL_T	$S$	double	0.0	time at which INITIAL_V and INITIAL_PHASE held
BETA		double	0.0	normalized load impedance
BIN_SIZE	$S$	double	0.0	bin size for current histogram (use 0 for autosize)
N_BINS		long	20	number of bins for current histogram
PRELOAD		long	0	preload cavity with steady-state field
PRELOAD_FACTOR		double	1	multiply preloaded field by this value
RIGID_UNTIL_PASS		long	0	don't affect the beam until this pass
DETUNED_UNTIL_PASS		long	0	cavity is completely detuned until this pass
SAMPLE_INTERVAL		long	1	passes between output to RECORD file
RECORD		STRING	NULL	output file for cavity fields
SINGLE_PASS		long	0	if nonzero, don't accumulate field from pass to pass
PASS_INTERVAL		long	1	interval in passes at which to apply PASS_INTERVAL times the field (may increase speed)
FREQ_WAVEFORM		STRING	NULL	$<$filename$>$=$<$x$>$+$<$y$>$ form specification of input file giving frequency/f0 vs time, where f0 is the frequency given with the FREQ parameter
