Phone Conference Summary  August 12, 1998
        ==========================================

Attending: Scott, Hodges, Sutton, Wright, Mundy 
           (Shepherd -- late due to my error)

Modeling of the B-array using the measured pads was done by Shepherd 
and Mundy. The conclusion was that the new position for SW6 was ok. 
The sidelobes are a little higher for declination -5 than for the 
requested position but not enough to justify repositioning SW6. The 
B-array is the the only one that uses SW6. The other star pads were close 
enough to the requested positions that changes are minor.  Mundy will 
produce final beams and coverages when all of the pad locations are 
finalized.

The various alternatives for A-array configurations were discussed.
We defined: 
    Option 0 = Array from section 1 of memo of August 1998. It 
               includes the N9 pad.
    Option 1 = option 1 from section 2 of memo of August 1998. It
               has the same resolution as option 0 but drops N9
               and adds stations to the south.
    Option 2 = option 2 from section 2 of memo of August 1998. It drops
               N9. It has lower resolution than options 0 or 1 and has
               lower sidelobes for source declination of -5 degrees.
               It should be the least expensive option due to shorter
               baselines and less stations off the main star.

Steve discussed the possibility that the access road could take a northern
route passing by N9 -- which would cancel out the originally perceived 
negative environmental and cost impacts of N9.  It was generally agreed 
that more resolution was better, although Ed expressed some preference 
for the lower sidelobes of option 1. 

We officially rank options 0 and 1 as preferred and agreed that the
final choice could be influenced by the route chosen for the access
road.

Mark Hodges talked about the work that he has done looking at the
horizon elevation limits. A few of the outrigger stations have
potential problems (ERS3, SW9, and perhaps ERN3) but all are likely
solved by moving the pad locations by 15-30 meters in the
appropriate directions. Ideally we would like to be able to observed
down to 15 degrees elevation in all directions, and down to 10 degrees
toward the southeast, south, and southwest (ie to observe the
galactic center and other southern sources).

Steve reported that the biology survey is proceeding; the field work 
should be done next week. The report is due October 1. The archaeology 
survey is not started; they are still negotiating on the proposed work.

The S-array has not yet been defined but it is not forgotten.

Action Items:
=============
1. Steve and Mark will measure locations for the new pads proposed
   in A-array options 1 and 2. They will measure the horizons for
   all the outrigger pads and move pads to try to comply with the
   target horizon limits listed above. They will also measure the
   road so it can be accurately put into our maps.

2. Lee will produce ps files of pad locations for overlays for the 
   Forest Service meeting. 

3. Short spacing array still needs to be designed.

Next Meeting: Some time in September.
