PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT INTERCHANGE_FORMAT = ASCII PUBLICATION_DATE = 2009-10-26 NOTE = "SCL-Kernel Information" END_OBJECT = TEXT END General information about SPICE SCL-kernels =========================================== In the SPICE system, the Spacecraft Clock Kernel (SCLK) contains information required to perform a mapping between Ephemeris time (ET) and spacecraft on-board time (SCLK). The spacecraft clock coefficient information contained in a SCLK file can be manipulated by a collection subroutines that are part of the SPICELIB library, the major component of the SPICE Toolkit. These subroutines can be integrated into user's application programs. Information about obtaining the SPICE Toolkit is located in the ``software'' subdirectory of the main directory of this dataset. Refer to the SCLK Required Reading (sclk.req) document provided with the Toolkit or available from the NAIF Node of the PDS, to get more information on how to convert between ET and spacecraft clock times. Hayabusa SCL-kernels Contained in This Data Set =============================================== This data set contains the following Hayabusa SCLK files (only the leading portion of the file name is shown; the extension of all file names is ``.tsc''): hayabusa SCLK file containing clock correlation data for the Hayabusa on-board clock, created by the Hayabusa Joint Science Team. All SCLK files provided in this data set are in UNIX text format, with a line feed character (ASCII 10) at the end of the line. Kernel File Details =================== The most detailed description of the data in an SCLK file is provided in metadata included in the descriptive text areas within the file. This information can be viewed using any text editor.
