(Left) Percentage of differences between the retrieved N₂ densities of flybys from Table A.1 using a temperature profile of 100 and 200 K. With a few exceptions, the difference is below 0.5%. Flybys T96, T97, T105, and T109 reach 30% of difference. (Right) N₂ retrieved densities for all flybys for a constant T profile of 150 K. The colours depend on the flyby, and the density points are stacked and averaged.
