3. CCD Calibrations Calibration Bias with warm and cold CCD
Covers all configurations except low power mode and dithering
Additional subframe bias before stellar calibrations
Full frame bias and dark images with s exposure time
CCD sync tests

4. NAC Dark image Lots of cosmics Note long stripe Several hot pixels
Exposure time 10 minutes
Lots of cosmics
Note long stripe
Several hot pixels
Apart from hot pixels very little dark current
Weak horizontal noise pattern

5. WAC dark image Lots of cosmics Several hot pixels
Exposure time 10 minutes
Lots of cosmics
Several hot pixels
Apart from hot pixels very little dark current

6. Internal lamps “Flat fields” with internal lamps with both cameras
1 uncompressed flat field for standard filter combination with main and redundant lamps
Compressed (ratio 6) flat fields in “all” other non-UV filters
Check of blocking of visible light in UV filters with uncompressed images, 8x8 binning

7. NAC with calibration lamps
Orange filter, 2 sec. exposure
Illumination not completely homogeneous
No obvious difference to images from the ground
Note intensity increase in first and last column

8. WAC with calibration lamps
Red filter, 1.25 s exposure
Illumination extremely inhomogeneous
No difference from ground calibration visible
Intensity increase in first and last column is present

9. Calibrations with open doors
Stellar intensity calibrations
ε Aqr, 59 Aql (secondary standards, early type)
Vega (primary standard)
16 Cyg (solar type, WAC only)
α Grus (very early type, Alice target, WAC only)
Stars also useful for focus, PSF, and spacecraft pointing relative to OSIRIS
“Random” star fields
Geometric calibration, PSF, focus, spacecraft pointing
Straylight at 90 deg. solar elongation
WAC: Neptune in the field of view

10. Vega with NAC and WAC
NAC, Filter neutral-orange
WAC, red filter

11. NAC Starfield Orange filter, 5 sec exposure
Taken on June 5
Orange filter, 5 sec exposure
Typical (not spectacular) field

12. WAC Starfield Red filter, 30 s exposure Note the mysterious stripes
Note the presence of straylight

13. Calibrations with open doors (2)
Planetary targets for solar-like calibration
Earth and moon
Venus
Saturn and Titan
Selected fields for geometric calibration
M42 and environment for WAC
Serves also for calibration of narrow band filters with line emissions
Area 98 for NAC
Also useful for PSF, focus, straylight,…

14. Earth and Moon NAC
NAC 3 color composite (blue, green, orange)
Logarithmic representation (moon is much darker than earth)

15. Earth and Moon WAC
WAC Na filter, 0.5 s exposure time
Logarithmic representation (moon is much darker than earth)
Earth slightly overexposed

16. Area 98 (NAC) Orange filter, 1 min exposure time
Rich field for accurate geometric calibration
Telescope tracking appears to be bad

17. M 42 (WAC) Na filter, 10 min exposure Logarithmic presentation
Orion nebula: Emissions + Continuum

18. Straylight test PR Solar elongation 20 – 140 degrees covered
Also test of spacecraft pointing stability
Strongly overexposed images of the Earth and the moon have been acquired during straylight test PR
Comet LINEAR 2002 (T7)
M42
Earth/moon system

19. Straylight NAC Orange filter, solar elongation 70 degrees
15 s exposure time, binning 4x4
Overexposed earth offers nice opportunity to study ghosts

20. Straylight WAC Red filter, solar elongation 70 degrees
0.75 s exposure time, binning 4x4
Straylight up to ~5000 counts in first rows (note binning, though)
Ghosts of overexposed earth (and moon)

21. OSIRIS NAC Multicolour Image
(blue, green, orange)
Comet C/LINEAR 2002 T km distance – 1. May 2004

22. NAC colour composite of M42

23. Other Calibrations High-speed imaging test
Maximum image repetition rate
Test of image transport through plainfile
Handling of large data volumes
Test of low power mode
Test of transmission of science data through housekeeping link

24. Current and future operations
Currently RSOC commissioning
Test of interface experimenters/RSOC/(RMOC)
Four “routine scenarios” for comet observations are simulated
Dry test (no observations performed)

25. Operations 2005 Earth flyby 1
~3000 km flyby distance from the Earth
~ km closest approach to the moon
Observations of comet P/Tempel 1 during deep impact encounter (TBC)
2 payload checkouts
