Design Reference Science Plan - (Wootten )

Progress...I count about 90 proposals. I'm slowly going over them for sanity checks...Ewine and her student Jens have done a marvelous job of organizing them.

Discussion Item - (Wootten)

Calibration. Calibration (Butler)       - Calibration plan and milestones (Bryan)
                                                                                What people writing which section for what date.
                                                                      Telecon last week
                                                                       No further tests of amplitude devices??
                                                                       Accuracy of saturation measurements. Effland asked:

Tony Kerr and I have been measuring the saturation from room temperature loads of Band 6 mixer-preamps. We're trying to determine
if this measurement will be required for each mixer-preamp in the array. Do you have any idea how accurately saturation must be
measured?
Response: The current calibration goal is 1%. I think the ASAC will set the specification somewhat looser, perhaps 3% Band 6, as we don't see how we can reach 1%. I'm not sure what the saturation will be but as I recall something like 3%. To have measured something at all, it should be
5 sigma, so I would think that a 10% measurement would be good. That then would amount to 10% of our specification and a third of our goal. Of course, I should know from the FE Group what is possible also! What does the group think?

ALMA Receiver stability
A further telecon may be planned for 1430 UT on 27 August.

Science Requirement document (Butler)

ALMA Science Requirements document under construction provides a succinct flowdown from the Project Plan; Preface to Engineering Requirements document nearing completion.

Configuration (Wootten)

Extended Array (Holdaway) Document ALMA-90.02.00.00-002-A-SPE submitted. Comments?
Move Sequence (Conway) Note that the four TP antennas cause some problems in defining the resequencing. One solution is to assume that they will be assimilated into the ACA. Ewine and I recommended doing that for now.
