The file containing the bands of a calibrated radiance image, using the WATTS units.
The first output dataset is a halfword image of all the input bands of
emittance data, scaled such that an emittance of 1.0 is 10,000 DN.
The second output dataset is a halfword temperature image, where each DN
corresponds to 0.01 degree Celsius. 0 DN corresponds to 0 degrees C.
The standard VICAR2 output size field. Default will calibrate the entire data set. Example: SIZE = (1,1,200,638)
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 channel to which the other bands are to be referenced, in the case of REFCHAN mode, is input through this parameter. In BBFIT and ALPHA modes, this parameter is ignored. Example: REFCHAN = 5
In REFCHAN mode, the spectral emittance of the reference channel is
set to a constant value, given by this parameter.
In BBFIT mode, spectral emittances are computed so that the maximum
of the six emittance values is equal to the value of E.
TEMIS needs the center wavelength for each band of the input. The
Variables CWAVE, FILFILE or DATE are used to specify those wavelengths.
Only one of the three variable should be specified
CWAVE is an array of the center wavelengths (nicrons) that
corresponds to the bands of the input file (in micron
FILFILE is an ascii file that contains one filter function for
each input band. each filter is started by a line containing
the string " band" and should consist of two columns, the first
the wavelength in microns and the second the response at that
wavelength
DATE is the TIMS flightline date for the case of TIMS data. TEMIS
will retreive the filter funtion from timsfilt subroutine.
if none of these three parameters is specified, TEMIS looks in the
label for a TIMS format date, and if it finds one, retreives the
filter from the timsfilt subroutine.

An example of a filter file would be:
band 1
0.52 0.2
0.56 1.0
0.60 0.3
band 2
0.63 0.2
0.66 1.0
0.69 0.2
band 3
0.76 0.5
0.77 0.5
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 thrid method is the aplha residuals method.
The fourth method is to calculate the brightness temperature for each
band.
