Goals: - CIRS dark terrain scan
- High-res. imaging of "average" dark terrain

Pointing (pdt issues):
- Tracking start UTC: 2007-253T14:29:29 (IA+00:13:49 h)
- Tracking duration: 09:30 min.
- Tracking end UTC: 2007-253T14:38:59 (IA+00:23:19 h)
- Tracking location: -12/168
- CIRS scan (4 min.), then 1x1 mosaic (dwell = 5:12 min)

Exposures (ISSPT issues):
- ISSPT data volume: 21.1 Mb (all LUT)
- BOTSIM clr + N08 (2sum) + NP03 (2sum)


Radial smear:
  3.2s  2sum => ~1 pxl
  2s    2sum =>  0.65 pxl
  1s    2sum =>  0.32 pxl
  120ms full =>  0.08 pxl smear
