    11 Format appears to be 10 pairs of numbers (one each for channels 1-10).  The second number in a pair looks like the sensor value at the lit level, not sure of the first number (calibrated light level?  dark current value?).
     11Format is 10 pairs of numbers (one each for channels 1-10).  The first number is the gain (multiplier), the second number is the dark current level.  To compute a real world value, you should compute:
     12
     13`real world value = (sensor_DN - dark_current_level) * multiplier`
