[asac] receiver specs

[John Richer]

Hi all,

To echo Christine's comments, I think we do need to provide some
formal input from the SAC to Wolfgang and John fairly quickly - I
spoke to them yesterday and it's clear that they are happy for
feedback on the specifications document, but if they don't get any
they will simply adopt the proposed specs for the system.  They
emphasised that it was important to fix the specs early on, and avoid
changing them throughout the design process.  I wonder if our next
face-to-face meeting is early enough to send proper feedback, or if we
should do it sooner.  Specific issues of calibration and polarisation
specifications were uppermost in their minds, plus the issues of
coupling to the telescope and Rx temp spec.  Of course Stephane's
notes made some suggestions in these latter two areas. 

John
