Level 2 Help for MASTERHOT

The first file should contain the 10 channels of MASTER TIR image data,
calibrated as radiance at sensor, in units of Watts per square meter per
steradian per micrometer.

The second file should be the MASTER TIR spectra response calibration file 
(in VICAR format) that is in effect for the date of data acquisition.
These files are typically located in the directory 

          $V2TOP/luts

and have names of the form

         resp.master.tir.YEAR.MON

The output dataset will contain upwelling radiance at surface data for the
ten MASTER TIR channels (Channels 41 to 50), in units of milliWatts per
sqare meter per steradian per micrometer.  Output pixels are integer
(32 bit signed integer).  The units of the downwelling sky irradiance (values
placed in the VICAR label of the output) are milliWatts per square meter per
micrometer (no steradian term).

The standard VICAR2 output size field.   Default will process
the entire data set.
	Example: SIZE = (1,1,200,716)

Starting line (same as SIZE(1)).

Starting sample (same as SIZE(2)).

Number of lines (same as SIZE(3)).

Number of samples (same as SIZE(4)).

   The atmospheric and geometric parameters needed by this program to run
   MODTRAN are supplied by the user providing a valid MODTRAN input (TAPE5)
   file.  This file may be generated by the stand alone program "modin",
   or by any other means convenient to the user.

   As a default, the report file generated by MODTRAN is discarded 
   at the conclusion of the MODTRAN run.  If a dataset name is given
   as the parameter value to MODOUT, the report for the nadir looking case
   of MODTRAN is saved in that dataset.  If a dataset name is not given
   as a parameter, but one is supplied in the MODTRAN input file, then the
   report file is saved under that name.

   As a default, the tabular file generated by MODTRAN is discarded 
   at the conclusion of the MODTRAN run.  If a dataset name is given
   as the parameter value to MODTAB, the report for the nadir looking case
   of MODTRAN is saved in that dataset.  If a dataset name is not given
   as a parameter, but one is supplied in the MODTRAN input file, then the
   tabular file is saved under that name.
