INP=IN where IN is an image to be radiometrically corrected (byte or halfword).
OUT is the radiometrically corrected output image (16-bit data).
DIR specifies the default disk and directory location of all calibration files.
DIR may be specified as a VMS DISK:[DIR] or Unix pathname.
DIR=WMS_GLL:[SSI.RAD]
or DIR=/project/gll/ssi/rad/
DIR may be overridden for specific files via parameters DIRCAL, DIRDC, DIRBLM,
and DIROFF (see below).
DIRCAL=WMS_GLL:[SSI.RAD] (VMS)
or DIRCAL=/project/gll/ssi/rad/ (Unix)
DIRCAL specifies the directory location of the radiometric (slope) file.
When specified, DIRCAL overrides the default directory (see DIR parameter) for
the radiometric file only.
DIRDC=WMS_GLL:[SSI.RAD] (VMS)
or DIRDC=/project/gll/ssi/rad/ (Unix)
DIRDC specifies the directory location of the dark-current file.
When specified, DIRDC overrides the default directory (see DIR parameter) for
the dark-current file only.
DIRBLM=WMS_GLL:[SSI.RAD] (VMS)
or DIRBLM=/project/gll/ssi/rad/ (Unix)
DIRBLM specifies the directory location of the blemish file.
When specified, DIRBLM overrides the default directory (see DIR parameter) for
the blemish file only.
DIROFF=WMS_GLL:[SSI.RAD] (VMS)
or DIROFF=/project/gll/ssi/rad/ (Unix)
DIROFF specifies the directory location of the shutter-offset file.
When specified, DIROFF overrides the default directory (see DIR parameter) for
the shutter-offset file only.
STRING Input Radiometric File, as generated by program GALGEN. The Radiometric File's filter position must match the filter position of the input image. The filename should NOT include the directory of the file; refer to the DIR and DIRCAL parameters for specifying the directory.
STRING Input dark current file, in byte or halfword format. Dark current files may be (1) zero exposure frames, (2) a sum of zero exposure frames (see PICSUM), or (3) as computed by program GALGEN. The dark current file must match the input image in gain state and frame rate. Also, extended-exposure mode frames require extended-exposure dark currents. The filename should NOT include the directory of the file; refer to the DIR and DIRDC parameters for specifying the directory.
STRING Input Blemish File, as generated by program BLEMGEN. The filename should NOT include the directory of the file; refer to the DIR and DIRBLM parameters for specifying the directory.
STRING Input Shutter-Offset File, as generated by program CCDRECIP. The Shutter-Offset File is independent of all camera modes, and a single file may be used (for a fixed temperature). The filename should NOT include the directory of the file; refer to the DIR and DIROFF parameters for specifying the directory.
IOF=r where r specifies the output DN scale in number of 'I over F' units per DN. 10,000 'I over F' units would be produced by normal incidence of sunlight on a Lambert disk at Jupiter's distance from the sun (5.2 A.U.). The default is IOF=1.0.
CONV=r where r specifies the output DN scale in number of nanowatts per cm**2 per steradian per nanometer wavelength per DN. If not specified, the output is in units of IOF.
Keyword 'UBWC specifies uneven-bit-weight correction (default is 'NOUBWC).
Keyword 'NOCALC suppresses calculation of image entropy (default is 'CALC).
SOLRANGE=r
where r specifies the solar range (distance for target to sun) in km.
If not specified the following actions are taken:
(1) If the input image is in Phase1 format, the following constants are
used: Venus=0.723331 AU, Earth=1.0 AU, Gaspra=2.2016 AU, Ida=2.9485 AU,
Jupiter=5.2 AU.
(2) For Phase 2, SOLRANGE is extracted from the VICAR label.
(3) For ground calibration images, SOLRANGE=5.2 AU.
Keyword 'NOCHECK specifies that processing should continue even though the specified calibration files do not match the input files parameters: gain, frame-rate, filter & FIBE (where applicable). Warning messages identifying the suspected files are displayed along with a continuation with error message. The default is to terminate processing if mismatches are detected.
Keyword 'PRINT causes printing of the results of the entropy calculations for the entire image and for every 50th line (default is 'NOPRINT). Note that this keyword can be used to force the entropy to be calculated, even if it has been previously calculated by BADLABELS.
INTEGER--OPTIONAL (ground calibration data only) Filter position (0-7) FILTER=0 for Clear =1 for Green =2 for Red =3 for Violet =4 for 7560 =5 for 9680 =6 for 7270 =7 for 8890
INTEGER--OPTIONAL (ground calibration data only) Specifies camera gain state for input image. GAIN=1 for 400K (lowest gain state) =2 for 100K =3 for 40K =4 for 10K (highest gain state) The default gain-state is 4 for 800x800 images, and 1 for 400x400 (summation-mode) images.
INTEGER--OPTIONAL (ground calibration data only) Specifies the exposure time of the input image (msec).
INTEGER--OPTIONAL (ground calibration data only) Filter position for calibration file (0-7)
INTEGER--OPTIONAL (ground calibration data only)
Specifies camera gain state for calibration file.
CGAIN=1 for 400K (lowest gain state)
=2 for 100K
=3 for 40K
=4 for 10K (highest gain state)
The default gain-state is 2 for 800x800 images, and 1 for 400x400
(summation-mode) images.
INTEGER--OPTIONAL (ground calibration data only)
Specifies gain state for the Dark-Current File.
DCGAIN=1 for 400K (lowest gain state)
=2 for 100K
=3 for 40K

(summation-mode) images.
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.
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 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 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.
'DEBUG causes diagnostic messages to be printed (for debugging the program).
