Contour plots showing the confidence ranges of the fit values of Ne abundance vs. kT and S abundance vs. kT for regions cNE and lE. While the temperature kT is not well constrained, there seems to be a difference between the abundances of Ne and S, with Ne having a low abundance and S a high abundance. The contours are based on Markov Chain Monte Carlo method and correspond to 1, 2, and 3σ (dotted, dashed, solid lines).
