AO2: 
22:00:~ Notice that AO2 cals are not leveling off in 3-minute cal period for both HS and LS.  Sample values appear to be stable.
	Saved 2 PNGs that capture this.  
	Note that air was sucked into system at beginning of RF while plane was taxiing.  This is as per standard protocol
	but this time the spike was a bit larger than usual, to about -445 per meg, 391 ppm 
	(Li840 is reading about 10 ppm low, so showing atmospheric to be around 370)
	O2 signal: O2 "concentration" is increasing from -333 to 330 per meg over three minute period.
	CO2 signal: CO2 is increasing roughly 0.8 ppm from 396.7 to 397.5 
	O2 and CO2 signals are both increasing, suggesting this is not a leak
	
22:20:~ Noticed that most recent cal doesn't have problem to same extent.  Appears to be leveling off more quickly.

22:47:~ CylTemp1: 15.9 CylTemp2: 19.0
	Suspicion is that this drift has to do with cylinder temperature drift.  
	Britt mentions that ANC data lines up much better with MEDUSA than tropical data, perhaps due to this 
	same effect.
