Real-Time Observing

A workstation, connected to the on-line computers by an Ethernet link, is now in place at the VLA site. A special version of the AIPS task FILLM will fill VLA data into this workstation's disks in real time. Each scan is available for editing, calibration, and imaging with AIPS within a few seconds of the end of that scan. Data also can be written to a local Exabyte tape.

The real-time data pipeline also has been extended to the AOC. Any workstation at the AOC can now receive VLA data as it is produced. However, this capacity is not available beyond the AOC, as tests have given inconsistent results.
