The parameters in trace_plot.par are:
FILTER: The pass-band filter limits can be specified through the FILTER parameter.
DISTANCE: The distance range (y-axis) for the plot.
TIME: The time range in seconds (x-axis).
AMPLITUDE_SCALE: The amplitudes are scaled for every trace individually, by [amplitude/(max amplitude) * AMPLITUDE_SCALE].
STATION_SFILE_ONLY: This variable can be set to 1.0 to only plot traces that are listed in the S-file, the default is 0., which plots all traces without checking if they are present in the S-file.
TIME_ORIGIN: In the current version, the origin of the time axis corresponds to the origin time of the event.
COMPONENT: This can be used to select components for plotting, in case no component is defined, TRACE_PLOT will show all vertical component traces.
