Notes from conversation with Dick Gattinger:
- I overestimated the SNR available with an intensifier
- intensifiers help if you're worried about readout noise, but you lose
a factor of 5 signal right off the bat since the photocathode QE is only
0.1 instead of 0.5
- EEV make 1" CCDs with big (22u) pixels, so the optics can be opened up
- if the payload can be despun to 1 rpm we can reduce the horizontal
field of view to (say) 15 deg: optics are simpler and can be opened
further, helping SNR
- need to know (or model) pendulum-type oscillations: if they're not too
bad we can reduce the vertical fov and further gain signal
- include fairly detailed description of possible satellite follow-on:
platform stability, orbit, possibilities for tropospheric ozone
- Dick can send the WINDII star catalog (~15K stars down to M=9) if
necessary
