HYDRA at Pine Tower (forgot watch so times nebulous -- around 10:30 - 11:00)
		Connect to 3-way valve with quick connect 
		On line D-S3. Sample Ball Flow = 35. Pump Pressure = 8.1 psi.
		Switch to gas A. 
		Done adjusting regulator to get Flow = 35, Pressure = 8.2 psi.	
		CO2 = 59.96 - 60.00 um/m. 
		Step 3-way to B. 
		Adjusted regulator to get Flow = 37, Pressure = 8.2 psi.
		CO2 = 16.42 - 16.49 um/m.
		Step 3-way to C. 
		Adjusted regulator to Flow = 35, Pressure = 8.2 psi.
		CO2 = 35.25 - 36.35 um/m.
		3-way back to HYDRA.


CU Tower
11:45 MDT	Switched profile to manual. Toggled C2.
11:48		P = 20.3 psig.	3-way to ICS, Cylinder A
11:52		Step 4-way to B
11:54		Regulator adjusted to get 20.4 psig, CO2 = 1.110 
11:56		Step 4-way to C
11:57		Regulator adjusted to get 20.6 psig, CO2 = 1.181 
11:59		Toggled C2. CO2 = 1.258
12:00		Back to Auto.

USGS Tower

11:11:50 MST	Sampling line 2, P = 543.58
11:13:00	Switched 3-way to start ICS, Cylinder A
11:14:30	Adjusted regulator to get 543.58
11:16:30	Step 3-way to B.
11:17:30	Done adjusting regulator to get 545.89
11:19:30	Step 3-way to C.
11:20:30	Done adjusting regulator to get 546.55
11:23:00	Switched 3-way back to sample from towers, line disconnected

AIRCOA B Aspen site
18:55:50	Took control. 
18:56:30	Open V11, V12. Gas A. Adjust regulator to 10. 
18:57:30	P = 77.276, F = 2.882 
18:58:00	V12 turned off.
18:59:00	P = 71.027, F = 1.427, CO2 = 389.8 - 390.9
19:00:18	Switch to gas B
19:00:35	V12 on 
19:01:22	Close V12
19:02:36	P = 70.933, F = 1.395, CO2 = 319.5 - 320.2
19:03:50	Switch to C 
19:03:54	V12 on
19:04:51	V12 off
19:06:09	P = 70.919, F = 1.382, CO2 = 348.7 - 350.3
19:06:50	Return unit control to Prometheus
