Level 2 Help for IBISNAV

OUT

STRING--A VICAR labelled file with IBIS data structure.  See help file
for description of file format.


FILENAME

The name of an ASCII text file containing a list of filenames:

	/home/gmy/s001245663.img
	/project/gll/s004455667.abc
	/project/gll/s987654123.img

The file may be created via a text editor.

A maximum of 50 images can be included, one per line.  The filename cannot
exceed 80 characters.  The list should contain images of the same target and
be listed in the order of priority for the mosaic.

The FILENAME parameter overrides the SCET and CAMERA parameters.


CKNAME

STRING - A list of C kernel types, one for each image, indicating the preferred
source of the SPICE camera pointing information.

Valid values are "DAVI","NAV ","FARE","NAV2","NEAR","AMOS", and "SEDR".

If CKNAME is defaulted, or if the preferred source is not available,
the best available camera pointing will be substituted (in the order listed
above).


CAMERA

INTEGER - List of camera serial numbers, one for each image.
Not required if FILENAME keyword used.

Voyager camera serial numbers:

        4 = VGR-2 WA            6 = VGR-1 WA
        5 = VGR-2 NA            7 = VGR-1 NA

Galileo SSI camera serial numbers:

	1 = full frame
	2 = summation mode

Cassini ISS camera serial numbers:

        1=NAC full frame	2=WAC full frame
	21=NAC 2x2 summation	22=WAC 2x2 summation
	41=NAC 4x4 summation	42=WAC 4x4 summation


SCET

Integer - The spacecraft event time for each frame in the mosaic.
Not required if FILENAME keyword used.

The SCETs are entered as groups of 6 integers, representing the year, day
hour, minute, second, and millisecond:

        SCET=(1998,212,18,54,32,213, 	      1998,212,19,2,30,214,  	      1998,212,19,10,28,212)


PROJECT

String - The project ID. Valid are:
VGR-1  VGR-2  GLL


TARGET

REQUIRED PARAMETER

Name of target body (planet, satellite, or asteroid).

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

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


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.


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.
