Tom Sargent:
     1. Out sick on Monday
     2. I wanted a 3-d plotting program to view the sun avoidance path 
        calculations to see if they do actually avoid the sun. Since 
        it seemed likely we would be using GTK+ for various user 
        interfaces, I studied it for a couple of days and got a couple 
        simple examples to run.   I then wrote a 3-d plotter program.  
        It draws wire-frame type models in 3-d perspective in an X 
        window. This is now working.  A small addition to it will make 
        it draw stereo pairs.  I now need to code the sun avoidance 
        geometry that I worked out last week and then use the 3-d 
        program to show the solar zone-of-avoidance and the paths 
        which the program picks to go around it.

Pete Hubbard:
     1. Comparing  data sheets PMI REF43 and MAX 6325 Voltage 
        Reference chips. The Maxim has much better temperature 
        coefficient and lower noise. This will provide the +2.5 volts, 
        and an inverting amplifier like the OP77 can provide -2.5 
        Volts. I also looked at using a INA105 amplifier that has 
        matched resistors inside the chip, but it can only drive 300Pf  
        loads. With amplifier bypass caps of .01uF they may not work 
        properly.
     2. Robert E. looked for spare connectors that will be needed for 
        amp boards and did not fine any at SMT or the lab.
