+Interstellar Mapping and Acceleration Probe Dynamic Frames Kernel
+========================================================================
+
+   This kernel contains SPICE frame definitions to support the IMAP mission.
+
+   To be consistent with conventions prior to the mission name change
+   from Solar Probe Plus (SPP) to Parker Solar Probe (PSP) in 2017, frame
+   names and other text IDs are prefixed with the legacy acronym, SPP.
+
+Version and Date
+---------------------------------------------------------------
+
+   The TEXT_KERNEL_ID stores version information of loaded project text
+   kernels.  Each entry associated with the keyword is a string that
+   consists of four parts: the kernel name, version, entry date, and type.
+
+   SPP Dynamic Frame Kernel Version:

+Implementation Notes
+---------------------------------------------------------------
+
+   This file is used by the SPICE system as follows: programs that make use
+   of this frame kernel must `load' the kernel normally during program
+   initialization.  Loading the kernel associates the data items with
+   their names in a data structure called the `kernel pool'.  The SPICELIB
+   routine FURNSH loads a kernel into the pool as shown below:
+
+      FORTRAN: (SPICELIB)
+
+         CALL FURNSH ( frame_kernel_name )
+
+      C: (CSPICE)
+
+         furnsh_c ( frame_kernel_name );
+
+      IDL: (ICY)
+
+         cspice_furnsh, frame_kernel_name
+
+      MATLAB: (MICE)
+
+         cspice_furnsh ( frame_kernel_name )
+
+   This file was created and may be updated with a text editor or word
+   processor.
+
+
+IMAP Dynamic Frames
+---------------------------------------------------------------
+
+   This frame kernel defines a series of dynamic frames listed in [3]
+   that support Parker Solar Probe data reduction and analysis.  All
+   of the frame names defined by this kernel are prefixed with 'SPP_'
+   (the legacy mission name acronym as described in the leading paragraph
+   of this file) to avoid conflict with alternative definitions not
+   specific to the project. Further, the project-specific ID codes
+   -96900 to -96999 have been set aside to support these dynamic frames.
+
+   The following dynamic frames are defined in this kernel file:
+
+      Frame Name               Relative To              Type     NAIF ID

+IMAP Spacecraft Clock Kernel (SCLK)
+===========================================================================
+
+     This file is a SPICE spacecraft clock (SCLK) kernel containing
+     information required for time conversions involving the on-board
+     IMAP spacecraft clock.
+
+Version
+--------------------------------------------------------
+
+     IMAP SCLK Kernel Version:
+
+     IMAP Version 0.0 - April 12, 2023 -- Ian W. Murphy
+        The initial IMAP spice kernel.
+        This file was created by using DART initial kernel and
+        modifying the spacecraft ID.
+
+
+Usage
+--------------------------------------------------------
+
+     This file is used by the SPICE system as follows: programs that
+     make use of this SCLK kernel must 'load' the kernel, normally
+     during program initialization.  Loading the kernel associates
+     the data items with their names in a data structure called the
+     'kernel pool'.  The SPICELIB routine FURNSH loads text kernel
+     files, such as this one, into the pool as shown below:
+
+        FORTRAN:
+
+                  CALL FURNSH ( SCLK_kernel_name )
+
+        C:
+
+                  furnsh_c ( SCLK_kernel_name );
+
+     Once loaded, the SCLK time conversion routines will be able to
+     access the necessary data located in this kernel for their
+     designed purposes.

+Kernel Data
+--------------------------------------------------------
+
+     The first block of keyword equals value assignments define the
+     type, parallel time system, and format of the spacecraft clock.
+     These fields are invariant from SCLK kernel update to SCLK
+     kernel update.
+
+     The IMAP spacecraft clock is represented by the SPICE
+     type 1 SCLK kernel.  It uses TDT, Terrestrial Dynamical Time,
+     as its parallel time system.
+
+\begindata
+

+\begintext
+
+     In a particular partition of the IMAP spacecraft clock,
+     the clock read-out consists of two separate stages:
+
+                           1/18424652:24251
+
+     The first stage, a 32 bit field, represents the spacecraft
+     clock seconds count.  The second, a 16 bit field, represents
+     counts of 20 microsecond increments of the spacecraft clock.
+
+     The following keywords and their values establish this structure:
+
+\begindata
+
+SCLK01_N_FIELDS_43          = (            2 )

+SCLK01_OFFSETS_43           = (            0           0 )
+SCLK01_OUTPUT_DELIM_43      = (            2 )
+
+
+\begintext
+
+     This concludes the invariant portion of the SCLK kernel data.  The
+     remaining sections of the kernel may require updates as the clock
+     correlation coefficients evolve in time.  The first section below
+     establishes the clock partitions.  The data in this section consists
+     of two parallel arrays, which denote the start and end values in
+     ticks of each partition of the spacecraft clock.
+
+     SPICE utilizes these two arrays to map from spacecraft clock ticks,
+     determined with the usual modulo arithmetic, to encoded SCLK--the
+     internal, monotonically increasing sequence used to tag various
+     data sources with spacecraft clock.

+
+     The remaining section of the SCLK kernel defines the clock correlation
+     coefficients.  Each line contains a 'coefficient triple':

+         Corresponding TDT Epoch at which Rate is introduced.
+         Rate in TDT (seconds) / most significant clock count (~seconds).
+
+     SPICE uses linear extrapolation to convert between the parallel time
+     system and encoded SCLK.  The triples are stored in the array defined
+     below.
+
+     The first time triplet below was entered manually and represents the
+     approximate time (in TDT) at which MET = zero.  The current plan for
+     IMAP is that the given epoch will be used for both Observatory I&T
+     and launch.  Note that the conversion from UTC to TDT used 34 leap
+     seconds.
