3) Documents
To be ready 2 weeks in advance for distribution, specially to the outside members. We already have a lot, but are weak on operation issues. Gross distribution
- Nested Ring concept (Yun / Butler)
- Spiral concept (Conway)
- Multi-configuration aspects (Viallefond)
- Compact array issues (Morita / Guilloteau)
- Site issues (Radford / Butler)
- Operation concepts (Wootten / Guilloteau) (oops, have to work here...)
- Cost issues (Hofstadt / ? )
Goal of the meeting: select a baseline design to continue with detailed implementation work ...
The CLEAN and difference results for B arrays for all three declinations and all five test images, with directly comparable grey scale difference images, have been posted on my website, available under Steven's Lair. This now shows CLEAN and difference images for all declinations and test images, with the grey scale difference plots directly comparable. Opinins?
Steven calculated fidelity images for the CYG, MPD and SDC examples for the B resolution at the same time as the C array ones posted earlier, so has posted them for perusal at his site.
Are the procedures used sensible? How do we improve on this? How do we make use of the outputs?
Koh-Ichiro Morita has made a summary of my recent imaging simulations for ACA. The summary may be seen at this URL. Any comments or questions are welcome.
Brief summary:
Please read Advance of Alma simulation at IRAM by F. Gueth, S. Guilloteau, R. Moreno and J. Pety considering the performance of ALMA with the ACA.
Simulation Strategy outline at the Tucson meeting is found here. What changes should we adopt based on our experiences so far?
The plans for the layout of the pads must be finalized by the beginning of construction. We hope that the first construction funds will arrive on 2001 Oct 1 when the FY2002 begins here. The project WBS has this date as 2002 Jan 1. Realistically, I think we need to inspect the pad sites before finalizing their location. As a start, Wootten compared pad locations for the spiral and nested ring arrays, and Butler and Radford did some studies in December 2001. There exists a list of possible problem pad locations for the 3km 1.6km and 0.8 km and Spiral array. Hopefully, these sites are, in fact, OK. Are there any others which folks have worried about?
Next Meeting?
