 == Collaboration meeting talks ==
-- After some discussions we decided to have the following talks: Tracking (Simon), CDC update (Mike), FDC update (Lubomir), TR studies with spare package (Lubomir) 10min., f125 Update (Cody) 10 min. Naomi will come with an agenda for the collaboration meeting on the next DC meeting.
+- Everybody at the meeting agreed with the agenda for the collaboration meeting.
 == Gas puzzle ==
-- Latest results from the CO2 sensor shown above: first plot using pressure correction that works for the CDC, second plot pressure correction that makes the certified gas measurements flat.
+- Last CO2 results linked above
-Conclusion: the C02 percentage in the CDC has stabilized at about 52-53%. Curtis: we need to do measurements and then decide if we want to change the gas mixture. At some point we need to add also alcohol to the gas.
-- Fernando: how stable the CO2 percentage should be. The way it works: one should correct for/calibrate the gas as often as possible. Naomi has simulated different gas mixtures. Also, one should correct for the pressure dependence - 1% pressure change results in 7% change of the amplitude.
