These web services are the back-end of the MWA triggering system, described in detail Hancock et al, 2019 (https://ui.adsabs.harvard.edu/link_gateway/2019PASA...36...46H/EPRINT_PDF)

  • start_time: The earliest time in GPS seconds for which data should be saved - if zero, or before the earliest buffer file available save all data. This value is inclusive, so .free files later that, or starting at this time, are included.
  • end_time: The latest time in GPS seconds for which data should be saved. If start_time and end_time are both zero, don't save any data. This time may be in the past. If not specified, keep capturing until 'obstime' seconds into the future, from the time of calling.
  • obstime: How many seconds to keep capturing data for, after the buffer dump (from 'now' into the future, not including past data dumped from the buffers). If end_time is specified, the value of obstime is ignored.

For triggers requiring continued capturing after the trigger, you would normally pass zero to start_time, and a duration to obstime as a capture duration, counted from the time that the trigger takes place. For captures requiring only one or two subfiles at a specific time in the past, you would pass specific GPS times to start_time and stop_time, and not use obstime.

Note that if start_time and end_time are both specified, and both zero, no subfiles are captured, but otherwise the full end-to-end process takes place as a null operation, including calls to all 24 MWAX servers.

The structure returned is a JSON encoded dictionary, containing the following:
