-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?).
+Format 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:
+
+`real world value = (sensor_DN - dark_current_level) * multiplier`
