Help for TEMIS

PURPOSE:
     TEMIS is a program to generate spectral emissivity images from
calibrated radiance data. The input dataset should be the calibrated
(IRAD or GRAD) channels. The first output will contain the spectral
emittance images for each input band, while the second output will
contain the temperature image.
     Three algorithms (MODEs) have presently been implemented. The first
method, called REFCHAN, sets a specified reference channel to a specified
constant emittance value. The default sets Channel 6 to 0.95. The temperature
is computed based upon the radiance and given emittance of the reference
channel, then the other five spectral emittances are computed, using this temperature.
     The second method, called BBFIT, assumes that the highest spectral
emittance is at a user-specified level (default = 0.95). It then computes the
highest temperature consistent with this assumption, and the six spectral
emittances, based upon the computed temperature.
     The third method, ALPHA, uses the alpha residuals method
