SP SCLK File -- TEST DATA
===========================================================================

   This file is a SPICE spacecraft clock (SCLK) kernel containing
   information required for ExoMars RSP Surface Platform Module (SP) 
   on-board clock to UTC conversion.
   
   This file contains the data necessary for converting from ET to
   ticks for the SP spacecraft clock (clock ID code 173)
   
   This is intended for testing purposes.
     

Production/History of this SCLK file
--------------------------------------------------------

   This file has been created by Stanislav Bober (IKI) based on: 
   - SP SCLK kernel "emrsp_sp_fict_20191031.tsc",
   - SPOCC SVT0.2 dry run results,
   and contains TEST DATA. 
   It is intended ONLY for testing purposes. 
   NO DATA ANALYSIS SHALL BE PERFORMED BASED ON THIS FILE.
   
   This SCLK kernel is intended to be used with test CK files with
   structure IDs listed below on board the surface platform -173 (SP):

      SP_LANDER             -173000
      

Usage
--------------------------------------------------------

   This file must be loaded into the user's program by a call to the
   FURNSH subroutine

          CALL FURNSH ( 'this_file_name; )    -- FORTRAN
          furnsh_c ( "this_file_name" );      -- C
          cspice_furnsh, 'this_file_name'     -- IDL
          cspice_furnsh( 'this_file_name' )   -- MATLAB
          spiceypy.furnsh( 'this_file_name' ) -- PYTHON

   in order to use the SPICELIB SCLK family of subroutines to convert
   SP_LANDER spacecraft on-board clock to ET and vice versa.


SCLK Format
--------------------------------------------------------

   The on-board clock, the conversion for which is provided by this SCLK
   file, consists of two fields:

          SSSSSSSSSS.FFFFF

   where:

          SSSSSSSSSS -- count of on-board seconds

          FFFFF      -- count of fractions of a second with one fraction
                        being 1/65536 of a second; normally this field value
                        is within 0..65535 range.

Kernel DATA
--------------------------------------------------------

   The data used to generate this kernel has been obtained from the test
   time correlation packets for SP and processed in order to insert an
   additional time correlation packet (TCP) between each pair of original
   valid TCP records to force continuity between them.
 
   Each TCP record inserted has the UTC "validity start time" equal to
   the time of the second TCP record in each pair minus 60 seconds. The
   on-board clock (OBT) value for this extra packet is computed using the
   gradient from the first TCP record in the pair, while the gradient of
   the extra packet is computed so that the linear function ``passes''
   through the extra packet's UTC/OBT point and through the second
   packet's UTC/OBT point, thus forcing continuity between the two original
   trends.
