Coronal Fe XIII emission line in CN Leonis
This chart represents a "decomposition" of an emission line at wavelength 3388.1 Ångstrom (338.81 nm) into two components. The observed spectral intensity is indicated by the ''step''-curve (in blue). As will be seen, the sum (fully drawn red line) of a strong and narrow line from titanium ions (Ti II) in the stellar chromosphere (dashed, in red) and an underlying, much broader, coronal line from 12 times ionised iron (Fe XIII; dashed, in red, slightly to the right of the titanium line) fits the observed spectral intensity curve perfectly.
