Minutes
- Yougang presented work he and others are doing with SKA, MeerKAT, and FAST. New antennas for SKA will appear rather slowly over the next few years. He is making use of MeerKAT in the near term and described some FAST surveys that will overlap MeerKAT surveys. Students interested in working of FAST are welcome to talk with him. His slides are attached.
- Peter continued discussion from last time (Sept 16) about how the RIME includes the effects of mutual coupling. The key question he raised was whether the RIME depends on both the embedded element patterns (EEPs) of the antennas in an array and the scattering (S) parameters between the antenna 'ports'. Reza and Albert believe that the EEPs include all the information needed to compute the visibilities. The S parameters may be useful to know when designing an array but they are not needed to accurately compute the visibilties. Peter is not yet convinced, and believes that in order to 'correct' visibilities to account for mutual coupling, you need to know (by measurement or simulation) both the EEPs and the S parameters. Comments are welcome! Slides are attached below.
- Next discussion of the tNCCSz paper is Tues Oct 7.
- The Indico page for these meetings is now hosted by UW - Madison. We hope to transfer records of our previous meetings from Fermilab.
There are minutes attached to this event.
