The hardware interfaces will increasingly lean towards PCs and the pSOS operating system. This is new territory for the parkes environment, but not for the correlators, where we have now had several years of satisfactory results . The software architecture is largely complete. The present design has a simple command line interface. We are exploring the option of a Glish-based system.
Scheduling is still modest.
The calibration machinery is incomplete. The general design is unchanged. This is relevant only for frequencies above 4 GHz. This is unlikely to be easy, as the Bonn polarimeter expects an analogue signal centred on 300 MHz, and up to 500 MHz bandwidth. This topic was introduced here to outline the problem - it will be discussed at greater length at the next forum, when the picture should be a bit clearer.
