Notes. Eref denotes reference energy, Eobs is detected energy, N is normalization, and ΔC is the difference in the C-statistic with and without the line in question. The error bars were calculated for a 90% confidence interval and two interesting parameters. References.(a) Erickson (1977) (b) Grant et al.
