History

2005-02-08 Jeff Anderson - Original version

2005-08-24 Jeff Anderson - Fixed bug when algorithm was checking for the backside of the planet and convergence failed (checkHidden)

2005-11-16 Jeff Anderson - Fixed bug when a image covers more than 180 degrees in an orbit which would cause two focal plane roots to be inside the start/end time range.

2007-12-21 Debbie A. Cook - Added overloaded method SetGround that includes a radius argument

2009-03-02 Steven Lambright - Added an additional method of finding the point in SetGround(...) if the original algorithm fails. The spacecraft position at the beginning and end of the image are now being used to estimate the correct line if the bounding check fails the first time through.

2010-06-17 Steven Lambright - More tolerant of failures in the distortion models for finding the bounds of the search in FindSpacecraftDistance

2010-12-07 Steven Lambright - SetGround(double,double) now goes straight to the radius instead of using SetUniversalGround to get the radius.

2012-07-06 Debbie A. Cook, Updated Spice members to be more compliant with Isis coding standards. References #972.
