#include <CameraSkyMap.h>
Inheritance diagram for Isis::CameraSkyMap:
This base class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and sky (ra/dec). This class handles the case of framing cameras.
For internal use only.

| ) | [virtual] |
Compute ra/dec from focal plane coordinate.
This method will compute the right ascension and declination given an undistorted focal plane coordinate. Note that the ra/dec values can be obtained from the parent camera class passed into the constructor.
| ux | distorted focal plane x in millimeters | |
| uy | distorted focal plane y in millimeters | |
| uz | distorted focal plane z in millimeters |

| bool Isis::CameraSkyMap::SetSky | ( | const double | ra, | |
| const double | dec | |||
| ) | [virtual] |
Compute undistorted focal plane coordinate from ra/dec.
| ra | The right ascension angle | |
| dec | The declination |
what happens if we are looking parallel to the focal plane??
can lookC[2] == zero imply parallel
can this all be solved by restricting the physical size of the focal plane?
