NAME: SPICE_STANDARD_KERNELs USAGE: files = spice_standard_kernels(/load) PURPOSE: Provides fully resolved standard spice kernel filenames. files are downloaded if needed. NOTE: this routine is in development still. NAIF specifies a few "standard" files that must typically be loaded in before for any calculations can be performed. These are: Leap second kernel: (naif????.tls) Contains times of leap seconds. ???? contains the version number and increments by 1 with every new leap second. PCK kernel: (pck?????.tpc) Contains spin axis and size of most solar system bodies. SPK kernel: (de???.bsp) Contains ephemeris data for the planets. Mars (499) is NOT included in most recent version! The file names and locations (and even contents) of these kernels is not standard and will change with each new release. KEYWORDS: MARS: CALLING SEQUENCE: files=spice_standard_kernels(/load) TYPICAL USAGE: INPUT: none KEYWORDS: LOAD: Set keyword to retrieve and load file OUTPUT: fully qualified kernel filename(s) $LastChangedBy: $ $LastChangedDate: $ $LastChangedRevision: $ $URL: $
