Loading from flight 140913a
Data taken from NOx CPU c:\data\NOx

Data in flight appear normal.  Plume is prominently apparent.

It has been observed that the NO/NO2 ratios do not appear reasonable at low levels (<500 pptv).  There seems to be a constant artifact in the NOx channel.  This makes the NO2 reported high and should not be used directly.  For this flight, the NOx channel was run with the NO2 converter.  At first the artifact disappeared, but it came back.  Thus the NO2 channel should not be used.  These data are only preliminary.
