Provides the pixel at which the LMW starts, as the ratio of the average LMW value to the six pixel average value. The device specific pos should specify the valid ranges for each value. The format is the following: LMW position; ratio of LMWavg to 6 pixel avg. Additional information: Provides the pixel at which the LMW starts as well as the ratio of the average LMW value over a 6 pixel average value. A algebraic representation of this ratio is: Average of Light Monitor Window pixels ______________________________________ Average of 6 test point pixels The 6 test point pixels do not inlcude any of the Light Monitor Window. A sample return value would be '50;0.059;'.
