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
