Level 2 Help for DNTOXYY

Up to 10 multispectral registered input images.

Three Output REAL images in the order:
x    x chromaticity.
y    y chromaticity.
Y    Y tristimulus.

(Only required to create a new color calibration file.)
Colors of the known reference colors.
We list here all data for all the reference colors strung out in a long
list from color 1 to color M. Each color must contain (in this order):
1. x chromaticity in D65 (0 to 1.0).
2. y chromaticity in D65.(0 to 1.0).
3. Y tristimulus in D65. (0 to 100.0).
4. DN of this color in input image 1.
5. DN of this color in input image 2.   
6. .....etc....
 . DN of this color in last input image.
Repeat above for each reference color.
The number of reference colors must exceed the number of input images by 
at least 1. If COLORS is specified the MACBETH keyword is not required.

(Optional)
A table of the weights (priorities) of each color for the least squares fit.
The default is 1.0 for each color. If WEIGHTS is specified you must list a
weight for each color. If MACBETH is specified there are 24 colors.

(Only required to create a new color calibration file.)
The image location of the macbeth chart.
There are 8 input numbers in the order line,sample,line,sample,...
These are, in input order, the image coordinates of the centers of the upper
left, upper right, lower left, & lower right patches on the macbeth color
chart. The chart is oriented with the gray row at the bottom.
 With this information the program will go to the images and extract the
dn values for each of the 24 macbeth color patches. The program already knows
the Macbeth D65 colors. If MACBETH is specified the COLORS keyword is not
required.
NOTE: The coordinates are the image locations of the CENTERS of the corner 
patches.
