5. Do not see unusual stray light problems, but careful baffling is necessary.
6. Baselining 16 bit analog to digital converters. Could also use 12 bit A/D converters with multiple gains.
7. Baselining fixed filters on focal plane which requires stepping across focal plane. Advantage is the reduction in the number of mechanisms (filter wheel
8. Future Trade – consider placements of spectrographs so behind focal plane to
reduce stray light.
Modified Chandra orbit for complete observation of
~ northern or southern ecliptic in one orbit and equalizing
spectrograph and focal plane observation times.
Radius of perigee 3.0 Earth radii
Radius of apogee 24.5 Earth radii
Period 3.0 days
Height for data collection =/> 60 x 10^3 km
Time spent near perigee 12 hours
Time for focal plane observations 29 hours
Time using spectrograph 31 hours
