Detailed Description

Convert between undistorted focal plane and ra/dec coordinates.

This class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and sky (ra/dec). This class handles the case of line scan cameras.

2005-10-13 Jeff Anderson - Fixed a bug. Removed failure comparsion test on Sensor::SetRightAscensionDeclination calls. A failure indicated we didn't hit the target but we don't care here since the target is the sky.

bool Isis::CameraSkyMap::SetFocalPlane ( const double  ux,
const double  uy,
const double  uz 
)
virtualinherited

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.

Parameters
uxdistorted focal plane x in millimeters
uydistorted focal plane y in millimeters
uzdistorted focal plane z in millimeters
Returns
conversion was successful

Reimplemented in Isis::VimsSkyMap, and Isis::RadarSkyMap.

bool Isis::LineScanCameraSkyMap::SetSky ( const double  ra,
const double  dec 
)
virtual

Compute undistorted focal plane coordinate from ra/dec.

Parameters
raright ascension in degrees
decdeclination in degrees
Returns
conversion was successful
Todo:

what happens if we are looking behind the focal plane?????

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?

Reimplemented from Isis::CameraSkyMap.
