Sample input table follows fora 'typical' monitor. Note that the actual format of the input table
has no tabs in it. The values in the table are luminance values in cd/m2 that correspond to the
DAC values of input. The DAC column is included for clarity - the actual table in the .INI
(initialization) file contains only the values as listed under the Red, Green, and Blue columns.
These are listed sequentially in the file, starting with the values in the Red column, followed by
the Green, and then the Blue. Each table should have the same number of entries as identified
in the 'Count =' entry.
