Frames in this File
--------------------------------------------------------

     This frames kernel defines the topocentric frame at the PHX
     landing site OPS_080525 (Phoenix Landing Site OPS_080525):

        frame name .......... PHX_TOPO
        frame ID ............ -84900
        frame type........... FIXED
        relative to frame ... IAU_MARS

     This diagram shows the frame hierarchy:

PHX Topocentric Frame Definition
-------------------------------------------------------------------------------

     This frame defines the z axis as the normal outward at the landing
     site, the x axis points at local north with the y axis completing
     the right handed frame (points at local west.)

     Orientation of the frame is given relative to the body fixed rotating
     frame 'IAU_MARS' (x - along the line of zero longitude intersecting
     the equator, z - along the spin axis, y - completing the right hand
     coordinate frame.)

     The transformation from 'PHX_TOPO' frame to 'IAU_MARS'
     frame is a 3-2-3 rotation with defined angles as the negative of
     the site longitude, the negative of the site colatitude, 180 degrees.

     The landing site Gaussian longitude and latitude upon which the
     definition is built are:

        Lon = 234.299950 degrees East
        Lat =  68.452255 degrees North

     These Gaussian coordinates correspond to the following areocentric
     coordinates (R, LON, LAT) = (3376.300, 234.299950, 68.219987) and Mars radii
     (Re, Re, Rp) = (3396.19, 3396.19, 3376.20).

     The coordinates specified above are given with respect to the
     'IAU_MARS' instance defined by the rotation/shape model from the
     the PCK file 'mars_iau2000_v0.tpc'.

     These keywords implement the frame definition.

Landing Site Name to NAIF ID Mapping
--------------------------------------------------------

     This section contains keywords that map the lander and landing site
     names their NAIF IDs:

        \begindata

            NAIF_BODY_NAME += ( 'PHX' )
            NAIF_BODY_CODE += ( -84 )

            NAIF_BODY_NAME += ( 'PHX_LANDING_SITE' )
            NAIF_BODY_CODE += ( -84900 )
