1. Cube Generator Update
Todd Bradley
January 5, 2012

2. Update Since June, 2011 Meeting
Version for PDS is now able to accept both net cdf data files and pds .dat data files
Completed cube generator chapter for users guide
Online PDS version of cube generator is awaiting geometer

3. Cube Generator Chapter
A useful list in chapter that defines all of the geometrical variables produced by cube generator
Since Fall, 2011 I see a need to clarify a few of the geometrical quantities
Units of distance
Coordinate systems

4. Example of limb drift during Titan observation
Integration time = 240 seconds
Use “rayheight” from cube generator to show drift of field of view.
Cube generator returns datastruct2_initial, datastruct2, datastruct2_final, which is the geometry at the initial, middle and final times of an integration period, respectively.

5. Beginning of integration
Rayheight
S/C
Line of sight (spatial pixel 31)
Rayheight
S/C
Line of sight (spatial pixel 31)

6. End of integration (240 seconds)
Rayheight
S/C
Line of sight (spatial pixel 31)

7. Time = 240 seconds
Time = 0

8. Summary
No new updates to geometrical variables or returned data values
Open to suggestions and requests for additional variables and/or definitions
