This option is used to calculate the radius vector of maplets, the spacecraft vector, and the spacecraft pointing. In the menu shown below, V is the radius vector to the maplet, Z is the pixel/line image space locations of the landmark (i.e. the image alignment), and PTG/SCOBJ refers to the spacecraft pointing and position, nominal refers to the "initial" space pointing and position.

1. V from Z and pointing - Calculates the radius vector form the image alignment and the spacecraft data. This is the most commonly used "v" option.
2. Z from V and pointing - Moves images to the alignment predicted by the radius vector and the spacecraft position/pointing.
3. PTG/SCOBJ from Z and V (selected image) - Determines the spacecraft position and pointing based upon the image alignment and radius vector of the maplet. Make sure you have a stable system before you do this! You can move the spacecraft in the wrong direction if you are not careful! This option will as you to input a specific image on which to perform this calculation.
4. PTG/SCOBJ from Z and V (current images) - Similar to option 3 above, but does the calculation for all images added to the landmark.
5. PTG/SCOBJ from nominal (selected image) - Resets the spacecraft position and pointing to the nominal (i.e. original values determined for the mission). This option does it for a single image.
6. PTG/SCOBJ from nominal (current images) - Same as option 5 above, but for all images associated with the loaded landmark.
7. RA/DEC/TW (selected image) - Work in progress. This is the wobble program(?) R. Gaskell is developing.
