text=! Parkes Observing
Parkes antenna control is via a command line program called atsnap. atsnap will run a simple schedule and can take commands to stow/unstow the antenna etc. IF setup is done seperately - normal observers would not normally worry about this. Attenuation is done via the “loGUI” software. The VLBI backend consists of two “LBA DAS” which sample and filter the IF and the LBADR recorder which captures the sampled data, formats it in software and writes to local or remote disk (or streams for eVLBI). The DAS setup is controlled via the “DAS GUI” and the recorder via “cdisko2”. These are the same for ATCA, Parkes and Mopra and some documentation is available at:
All VLBI control is from the joffrey:2 VNC. Some generic Parkes control (such as receiver selection) are run from joffrey:1
The antenna is controlled via a commandline program called atsnap, run on joffrey. All LBA schedules should be i the directory
~pksobs/lba. Assuming the antenna is unstowed you can simply run a schedule as:
> cd ~/lba > atsnap vt999a.psn
where v999a, in this example, is the name of the experiment.
To stow the antenna, make sure atsnap is not running (^C if it is) and on a terminal on joffrey type:
> atsnap stow
Monitor in FROG that the antenna stows.
Check first on FROG the antenna really is stowed. If so, on a terminal on joffrey type:
> atsnap unstow
Monitor on FROG that the antenna moves out of stow position. The takes a few minutes - do not attempt to move the antenna until the unstow is complete. Note that atsnap does not return error messages - you can only tell the unstow failed by looking at FROG.

You should regularly monitor the following every 10-15 minutes
