Comments:

Install BG3 cables on BOTH DAS. Start with VC056 schedule and when fringes are found, switch to main schedule. Check appropriate profile to use at Parkes.

Running eVLBI

Run the eVLBI from the vnc session vulcan:1 (normal password).

This will have to be split as two separate correlations. Connect the recorders in the following way

Experiment needs to be split over both halves of CPSR2 cluster, using the following setup

Telescope DAS Recorder Pam Host Port TCP window
Parkes DAS1 pkvsi1 pam1 52100 64
Parkes DAS2 pkvsi2 pam3 52100 64
ATCA DAS1 cavsi1 pam2-ext2 52101 450
ATCA DAS2 cavsi2 pam4 52101 1300

Run the correlator with

> ./run-das1.sh > ./run-das2.sh

(run-fringe-das1.sh and run-fringe-das2.sh for vc056)

The recorders must be started after the correlator (within 30sec). The following is suggested:

Parkes DAS1 (pkvsi1)

vsib_record -p 52100 -H pam1 -m2 -f 1s -o “Parkes-DAS1” -t 12h

Parkes DAS2 (pkvsi2)

vsib_record -p 52100 -H pam3 -m2 -f 1s -o “Parkes-DAS2” -t 12h

ATCA DAS1 (cavsi1)

vsib_record -p 52101 -H pam2-ext2 -W 450 -m2 -f 1s -o “ATCA-DAS1” -t 12h

ATCA DAS2 (cavsi2)

vsib_record -p 52101 -H pam4 -W 1300 -m2 -f 1s -o “ATCA-DAS2” -t 12h
