Comments:

Command files for ATCA and Mopra schedules are on ftp site. ATCA schedule in place on leon.

Parkes .psn schedule on ftp site.

This is a 512/1024 Mbps test. It requires the new improved BG3 cable to be plugged in to the DAS correlator output ports and connected to the VSIC.

Parkes/Narrabri need to record with two DAS. Please make sure you use different names for the files on each machine (using the experimentname field in disko or directly in vsib_record). Set the second DAS to centre frequency 8489 MHz.

Please use the first hour for local tests (fauto, vsib_checker etc). Please aim on being ready for coordinated observing at 03:00 UT.

Disko does not support 64 MHz. Set the “Record Mode” to “Other”, “Number of bits” to 16 and “Compression” to “xxxx”. The data rate *must* be 512 Mbps. If using vsib_record, you just need to set the mode to 2 (-m 2). E.g.

 vsib_record -m 2 -t 3h -s 2005-03-09T03:00:00 -o vt07a1_Pa1
