Help for SEBASSTE

PURPOSE:
SEBASSTE is a VICAR program that converts a SEBASS radiance (preferably
ground radiance) image to temperature and emissivity images.  This is done
by a greybody fitting method.  A greybody spectrum of emissivity EMIS is
draped over the radiance spectrum until the radiance spectrum touches or 
pierces the greybody spectrum at KEY channels.  This determines the kinetic
temperature of the pixel, which is then used to compute the emissivity of
the remaining channels.
OPERATION:
SEBASSTE calculates temperature and emissivity in the following manner: 
First, the brightness temperature for each of the 128 channels of the pixel
is calculated. These 128 temperatures are sorted from high to low and the
channel of the KEY'th highest temperature is assigned an emissivity of the
value of EMIS.  Using this emissivity, the kinetic temperature is calculated.
Using this kinetic temperature, the emissivities of the remaining channels
are calculated.
