 This CK file was created using CKSPANIT Utility Ver. 3.0, November 6, 2006
 linked against SPICE Toolkit Ver. N0064.
 
 This file contains data from all type 1 and 3 segments from the source file:
 
       vg1_jup_version1_type1_iss_sedr.bc
 
 This data was packaged into type 2 segments stored in this file. The
 user-specified tolerance of  2.00000000000 SCLK ticks was used
 to expand each source data point into a window of constant orientation. The
 angular velocities for each point were set to 0 and clock rates were set to 1.

Orientation of the Voyager 1 Scan Platform during the Jupiter Encounter
=======================================================================
 
Version 1: Discontinuous, Uncorrected ISS SEDR Pointing
=======================================================
 
This is a Type 1 (discontinuous) C kernel containing pointing information for
the Voyager 1 scan platform during the Jupiter encounter. Note that the scan
platform's coordinate system is defined as coincident with that of the
narrow-angle camera.
 
This C kernel describes the pointing relative to the J2000 coordinate frame only
at the discrete moments when Voyager images were taken.
 
Data Summary
------------
 
This C kernel was generated using the pointing information encapsulated in the
"Supplemental Experiment Data Record" (SEDR) file for the Imaging Science
Subsystem (ISS). The SEDR file was originally generated shortly after the
Voyager flyby in Vax binary format. It was provided by the Multimission Image
Processing Laboratory (MIPL) at JPL.
 
Pedigree
--------
 
Only one correction has been applied to the SEDR data. The SEDR file provides
pointing information for both the wide- and narrow-angle cameras. These cameras
have a small offset, which is recorded in the Voyager Frames kernel. However, it
became apparent that the SEDR file was generated using an incorrect value for
this offset. The (incorrect) value used in the SEDR file was revealed as a
constant offset between the optic axes of wide- and narrow-angle images
shuttered simultaneously. By removing this offset, it was possible to determine
the orientation of the scan platform in a consistent manner, regardless of
whether the SEDR data described a a wide- or a narrow-angle image.
 
The C kernel was generated using SPICE program MSOPCK.
 
Accuracy
--------
 
Long experience with the SEDR file has revealed its pointing information to be
accurate to typically ~ 100 narrow-angle pixels, which is equivalent to ~ 0.05
degrees or ~ 1 milliradian.
 
This C kernel was generated by the PDS Rings Node. We hope to generate improved
C kernels (continuous and C-smithed) at a later date.
