(2) Report on the Antenna CDR - Welch

(3) Project Book, Polarization - Crutcher

For the first time in the joint project, there is an entry for all chapters in the project book. Please see The Project Book and comment. Chapter 5, on receivers, front end and WVR is of special interest.

Dick will discuss his concerns: 'I'm concerned that polarization seems to be getting shorted. I don't know of a single design decision that has been made to insure good polarization characteristics. Darrell's bandpass calibration method may be an exception, but even that does not seem to have high priority. Things seem to me to be going the way the usually do with radio telescope design. One discovers that to make polarization work well will compromise other things, so polarization is not given sufficient priority and polarization science is compromised. Examples of adverse decisions include not having a prime polarization receiver on axis, not having the ability to rotate the receiver package so linears at 45 degrees can be received, refusal to have a circular polarized feed system, etc.. The ASAC job is of course to make the science case, not to dictate how the science specs will be met. I have seen nothing reporting how the hardware and software groups are going to guarantee that polarization science can be done at the required levels.'
