Smoothes dedispersed time series data using a boxcar window (moving average smoothing). The data file should be in the SIGPROC .tim format.

Smoothing is a low-pass filtering operation, so one should be careful not to over-smooth the data as this may lead to fast pulsars being filtered out. As a rule of thumb, if you would like to see a pulsar of spin period X ms, the boxcar window width should be < X ms.

Usage:

• -h or --help: Display this usage information.
• -s or --skip time: Length of data to be skipped, in seconds (default is 0 s).
• -p or --proc time: Length of data to be processed, in seconds (default is all data).
• -w or --width width: Width of the boxcar window in milliseconds (default is 1 ms).
• -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:

Smoothes the data in data.tim with a boxcar window of width 2.5 ms, with graphics turned on, and in non-interactive mode. The output is written to data.smoothed2.5.tim.
