MSL Topocentric frame at JPL Mars Yard 
--------------------------------------------------------------------

This file contains definition of the MSL_TOPO frame at the JPL 
Mars yard. This kernel must be loaded into a user's program
using SPICELIB's LDPOOL routine in order to enable use of this frame.

This frame defines the z axis as the normal outward the surface,
the x axis points at local north with the y axis completing to the
right handed frame (points west). Positive azimuth is measured
counter clockwise from the x axis.

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

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

The Mars Yard coordinates used in this file were obtained by Frank
Jordan, Jim Campbell and Boris Semenov using the GPS receiver in
the Mars yard on February 18, 1998:

     longitude:  118 deg 10.318 arc.min west    ( 118.17197 deg )
      latitude:   34 deg 12.115 arc.min north   (  34.20192 deg )

Longitude and latitude measurements are supposed to be very accurate.

Version 1.0 -- Boris Semenov, x4-8136 -- February 19, 1998

Version 1.1 -- Boris Semenov, x4-8136 -- June 8, 2012

   Added name-ID keywords for 399100/JPL_MARS_YARD.

Version 1.2 -- Boris Semenov, x4-8136 -- August 4, 2013

   Made MSL-specific: changed 399100 -> -76900, JPL_MARS_YARD -> MSL_TOPO.
