desmear - Remove frame transfer smear
This program removes the frame transfer smear from a CCD
camera.

Programmer:  Tracie Sucharski, U.S.G.S., Flagstaff, AZ
             Algorithm from Andrew E. Johnson (aej@robotics.jpl.nasa.gov


ParmDescriptionDefault

ADDITIONAL NOTES:

ParmDescription
FROM
Input cube file name.  If the file extension is omitted,
then ".cub" will be assumed.
TO
Output cube file name.  If the file extension is omitted,
then ".cub" will be assumed.
XFERTIME
Time required to tranfer data from active imaging area
into the frame transfer buffer.

MER-MI = 10.24

OTYPE
Output pixel data type.  Permitted values are:
 NULL = output type is same as input file pixel type
    1 = 8-bit (integer with type conversion parameters)
    2 = 16-bit (integer with type conversion parameters)
    3 = 32-bit (floating point)
When processed data are being written back into the input
file, the output pixel type must be the same as the
existing pixel type in the input file.
ORANGE
Output pixel data range.  If ORANGE is NULL, then the
CORE_BASE and CORE_MULTIPLIER in the output file will be
set to represent the same range of data as the input file.

If OTYPE=1 (8-bit) or OTYPE=2 (16-bit), then the CORE_BASE
and CORE_MULTIPLIER in the output file will be set to values
that allow representing the specified range of output
values.  Output values outside this range will be stored as
a special "representation saturation" value.

The ORANGE parameter is ignored if OTYPE=3 (32-bit) since
the CORE_BASE and CORE_MULTIPLIER are not applicable to
floating point pixel values.

**NOTE** For a more detailed explanation of ORANGE, tutor
the orange.pdf.
