 Data are reported in this file only if the flask pairs had no statistically discernable difference at the 90-95% confidence level; if the standard deviation of the individual flasks within a pair is larger than the instrument precision determined by replicate injections, those results are not included here. Some additional culling of data is also based on relative magnitudes of flask differences within a pair.
