solardiv Documentation

solardiv - Divide/Multiply by BAND_BIN_SOLAR_FLUX from label
This program divides (or multiplies) each spectrum in a cube file by
the solar spectrum recorded in the BAND_BIN_SOLAR_FLUX keyword in the
BAND_BIN group of the file's label.  The MULT factor is
multiplied by the solar spectrum before dividing (or multiplying):

    OUTSPEC = INSPEC / (SOLAR * MULT)

        - OR -

    OUTSPEC = INSPEC * (SOLAR * MULT)

NOTE: The default value of MULT is 0.3183099, which is 1.0/pi.

ADDITIONAL NOTES:

Parm	Description
FROM	Input cube file name. If the file extension is omitted, then ".cub" will be assumed.
SFROM	SFROM specifies the subcube using a single string for all three dimensions of the cube. The order of the three dimensions is always "samples:lines:bands". If a dimension is left blank, all the data for that dimension is selected. The default value of NULL for SFROM selects the entire cube. Any application below can be used for any dimension. To select specific data from any dimension: "10-100(3):11,12,15-20:1-10(2)" = This example will select every third sample starting with sample 10 thru 100. It selects lines 11 and 12, and 15-20. It selects every other band, starting with band 1 thru 10. There are special characters that can be used for selecting a subcube efficiently, such as "*","#", and "~". For examples type "help sfrom" in TAE. **NOTE** For more examples and explanation of the many features of the SFROM parameter, tutor the sfrom.pdf or refer to Introduction To ISIS, Section 6, of the ISIS User's Manual **
TO	Output cube file name. If the file extension is omitted, then ".cub" will be assumed.
OPTION	Specifies whether to Divide (DIV) or Multiply (MULT) by the solar spectrum
MULT	Multiplication factor to be applied to the solar flux before it is divided/multiplied into each input spectrum. NOTE: The default value of MULT is 0.3183099, which is 1.0/pi. This will result in computing IOF when dividing radiance by the solar flux.
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.
USERNOTE	Comment from the user. This will be recorded in the ISIS session log file and also in the History entry that is put into the History object of the output file.
