gas analysisopacity

Flue gas analysis (top) and opacity (bottom).
The flue gas opacity at this point represents the raw ohmeter readings. Scaling issues will be addressed
once there is more data, and with some bench tests to determine % extinction.
(update, March 04/07: it appears that the laser is being absorbed by CO2, revised light source is described in HK-H11 )
The dips after 55 minutes correspond to pokes of the fire, when the door was opened, and track the
red flue temperature readings.
