Goals: - Highest-resolution complete
crescent of flyby
- High-res. mapping of bright north and south polar latitudes in Saturn shine
- Ridge NAC stereo partner for WAC 049IA_CASSREG request
- Landslide crater saturnshine imaging attempt
Pointing (pdt issues):
- 4-frames mosaic of illuminated crescent; dwell = 2:00 min
- 1x3 mosaic at south; dwell = 5:00 min/ftprt; covered latitudes: down to 45°S
- 1x3 mosaic at north; dwell = 5:00 min/ftprt; covered latitudes: down to 45°N
- Equator (ridge) at crescent; dwell = 3:11 min.
- 1x1 sit'n'stare over landslide crater (6°N/36°W in upper half of image)
(allows shorter read-out times); dwell = 14:05 min.
Exposures (ISSPT issues):
Crescent:
- N03 (2sum, all g=2): Uv3 26s; Grn 1.2s; Ir1 1.0s + NAC clr fullres. 1.5s
(g=2)
Saturnshine (poles):
- 3 NAC clr shutters: 32s (2sum, g=2); 2x 32s (fullres., g=3)
Ridge at crescent (stereo):
- N03 (2sum): Uv3 32s (g=3); Grn 3.8s (g=2); Ir1 3.2s (g=2);
- NAC clr 4.6s
- WAC clr 260ms (straylight test) + 120ms (both WACs in BOTSIMs)
Saturnshine (landslide crater):
- Eight long exp. 32s (fullres., g=3); two 2sum (46s + 32s, g=3)
Miscellaneous information:
- Saturn phase angle: ~35° (rev B/C was ~70°)
