MSL - SAM and CHEMIN, Discussion of the science/results from these instruments Options

CO2 and O2 peaks couldn't be a finger error in labelling plots could it?

The dent in the O2 peak when the CO2 is released seam reasonable.

The amount of CO2 and O2 is not really deducible from the plots. It gives only the MS detector count numbers. The ionization ratio is very different for the small molecules. A little bit of oxygen can give you a large peak while the same amount (number) of CO2 gives you a weak signal. I have no clue about the ionization ratio of both species.

Yeah the 4th sample looks kosher. I was thinking along the lines of an error in labelling in the first plot identified by Emily as a press release image.

The SAM results from EGU show significant differences to the previous ones. ...
The new results are from the same sample as the first ones were, so I don't know why the results are different. Maybe the heating was done differently.

On EGU 2013, Monday, 08 April 2013, Press Conference 1, "Latest results from the Curiosity Mars Rover", John Grotzinger told:

... and John Klein 4 gave us a different run where we changed the ramp, the temperature process by which the sample is run ...
