What does the scatter in the data mean? Is there a mixing between the ingassing composition and another endmember more similar to other inner solar system objects, is the fractionation during ingassing that large and variable, or could it be contamination?

I have two questions on your presentation: • In which minerals were your analysis carried out? As plagioclase in this meteorite partially remelted, does this have any implications on your measurements (e.g. scatter in the data)? • NWA 7325/8409 formed by impact melting of a gabbroic or anorthositic crust. Could nebular ingassing result from this stage, namely incorporation of nebular gases to a magma pond at the surface of the parent body?

nice talk. It looks like from your last supplementary slide that you never get into sputtering equilibrium (count rates continuously increasing). Does this worry you? Did you try higher-current or longer pre-sputter times?
