KPL/FK

   The auxillary frame ROS_HGA_AZ_EP/-226950 defined below has +X
   pointing along the direction from ROSETTA to Earth corrected for
   transmission ("downlink") case and Y pointing as close as possible
   to the geometric inertial velocity of ROSETTA relative to Sun.

   Using a CK co-aligning the ROS_HGA_AZ frame with this frame one can
   get an idelistic downlink-case HGA pointing with HGA's +Y axis
   contrained by Sun-centric s/c velocity rather mechaincs of HGA
   gimbals.
