Plot 4: Second temperature group for Log of level population ratio versus log of electron number density.
Plotratios: The level population ratios used in plots.
Population Ratios: All temperatures' level population ratios. (There are too many temperature inside our table. To see the full table in a correct version, please download it.)
Level Population Ratio Plots
The ratio for plot 2 of N(166278) and N(169088) with respeact to ground is too low for us to see them. There are no avaible graphs for those two.
