" END_OBJECT = TEXT END All NEAR geometry data are contained in a separate data set with 1 set per phase. These data sets contain geometry data in the form of SPICE kernels. The data set will contain: ik -- SPICE system for providing instrument orientation to spacecraft. ck -- SPICE system for providing attitude information for spacecraft and instrument platforms. ek -- EROS shape model kernels fk -- frames kernel directory. This directory is not used in NEAR lsk -- Leapsecond kernel for providing information to convert between UTC times and any other time system. pck -- Models used for rotations of solar system bodies and shapes (constants and matrices of planets and satellites). sclk -- Spacecraft clock kernel modeled against the time system TDT (Terrestrial Dynamical Time). spk -- NAIF ephemeris system - planet and spacecraft positions. plt -- SPICE plate model. grav -- gravity data.
