Level 2 Help for GSPICE

INP

Ex:  INP=/home/gmy/nicepicture.dat

Input image for which SPICE data is to be printed.

If INP is not specified, the SPACECRAFT, CAMERA, TARGET, and SCET parameters
must be specified.


SPACECRAFT

EX:  SPACECRAFT=GLL

Valid values are VGR-1, VGR-2, GLL and CASSI.  SPACECRAFT is only required if
INP is not specified.


TARGET

Ex: TARGET=GANYMEDE specifies that GANYMEDE is the target in the input image.

The TARGET may be a planet, satellite, or asteroid.  If defaulted, the target
name is extracted from the VICAR label or determined by other TBD means.

A complete list of valid target names is located in the ASCII file assigned
the logical name (or environmental variable) BODY_IDS.


CAMERA

Camera serial number.

Valid Voyager camera serial numbers are:
        4 = VGR-2 WA            6 = VGR-1 WA
        5 = VGR-2 NA            7 = VGR-1 NA
 
For Galileo, the camera serial number is 1 for full-frame images, and 2 for
summation mode images.

Valid Cassini camera serial numbers are:
     1=NAC  21=NAC 2x2 summation mode  41=NAC 4x4 summation mode
     2=WAC  22=WAC 2x2 summation mode  42=WAC 4x4 summation mode


SCET

Shutter centered Spacecraft Event Time of the image for which SPICE data is
to be printed.  SCET is only required if INP is not specified.


RING

Identifies the image to be a ring image.  The RING keyword is required if the
parameter INP is not supplied for a Galileo or Voyager image.  The RING keyword 
must be supplied if the INP parameter image is a Voyager image and the image is 
also a ring image.  The program uses the PA keyword value from a Galileo image 
label to determine if the image is a ring image, but there is not an equivalent 
for a Voyager image.


SPICEMODE

SPICEMODE=LOCAL specifies that SPICE data is to be retrieved from local
SPICE kernels.  SPICEMODE=REMOTE specifies that SPICE data is to be retrieved
via the SPICE server.  If SPICEMODE is defaulted, the logical name (or
environmental variable) DEFAULTSPICE is used to determine whether LOCAL or
REMOTE is used.  Note that if SPICE data is not found in LOCAL or REMOTE mode,
the other mode is attempted.


CKNAME

CKNAME is a four character string specifying the C-kernel to be used:

  CKNAME	C KERNEL
  --------      -------------
  DAVI		MIPS_DAVI.CK
  NAV		MIPS_NAV.CK
  FARE		MIPS_FARENC.CK
  NAV2		MIPS_NAV2.CK
  NEAR		MIPS_NEAR.CK
  AMOS		MIPS_AMOS.CK
  NAIF		the best NAIF kernel is used

If defaulted, the kernels are searched in the above order.


CKID

CKID is an alternative way to specify the prefered C-kernel (see CKNAME
parameter):

  CKID	  CKNAME	C KERNEL
  ----	  --------      -------------
  M906	  DAVI		MIPS_DAVI.CK
  M905	  NAV		MIPS_NAV.CK
  M904	  FARE		MIPS_FARENC.CK
  M903	  NAV2		MIPS_NAV2.CK
  M902	  NEAR		MIPS_NEAR.CK
  M901	  AMOS		MIPS_AMOS.CK
  varies  NAIF		there are a large number of these files

Ex:  CKID=M901 specifies the four character ID which uniquely identifies the
     C-kernel MIPS_AMOS.CK.

A complete list of the C-kernel IDs is located in the ASCII file assigned the
logical name (or environmental variable) KERNELDB.

If specified, CKID overrides the CKNAME parameter.


USERID

USERID is a three character string which identifies the user who created the
camera pointing.

Ex:  USERID=HBM identifies Helen Mortensen as the creator of the camera
     pointing.


GROUPID

GROUPID is a three character string which identifies the group which created the
camera pointing.

Ex:  GROUPID=040 identifies group 040 as the creator of the camera pointing.


INSTITUTE

INSTITUTE is a four character string identifying the facility which created
the camera pointing.

Ex:  INSTITUTE=MIPS specifies that MIPS created the camera pointing.


PURPOSE

PURPOSE is a four character string identifying the purpose of the observation
or the purpose of processing.  For example,
  PURPOSE=MOSA identifies the image as part of a mosaic sequence
  PURPOSE=COLO identifies the image as part of a color sequence


PROGRAM

PROGRAM is the first six characters of the program creating the camera pointing.

Ex:  PROGRAM=FARENC specifies that FARENC created the camera pointing.


SPKID

SPKID specifies the four character ID which uniquely identifies the
SP kernel used to create the camera pointing.  The SP-kernel IDs are located
in the ASCII file assigned the logical name (or environmental variable)
KERNELDB.

Ex:  SPKID=N015 specifies the SP kernel GLL_LONG_2.BSP


REQNUM

REQUNUM is a four character string identifying the IPL request number for
which the camera pointing was created.

Ex:  REQNUM=3456 identifies (somewhat) request number R123456


CDATE

Date and time the camera pointing was created in the form 'YEARMMDDHHMM'.

Ex:  CDATE=199602291200 specifies that the pointing was created at noon
     on February 29, 1996.
