Subtracts one time series data from another. This is useful in subtracting a smoothed version of a time series from itself (baseline subtraction). The data files should be in the SIGPROC .tim format.

Usage:

• -h or --help: Display this usage information.
• -n or --nsamp samples: Number of time samples read in one block (default is 4096 samples).
• -g or --graphics: Turn on plotting.
• -i or --invert: Invert background and foreground colours in plots (default is white on black).
• -e or --non-interactive: Run in non-interactive mode.
• -v or --version: Display the version.

Example:

Subtracts the time series in data.smooth1000.tim from data.tim with graphics not turned on. The output is written to data.sub.tim.
