(a) Line profiles of O III 52.57 nm, (b) O V 62.96 nm, and (c) Ne VII 46.52 nm observed at 15:29:30 UT, which are the results of double Gaussian fitting. The stars are the observed spectral irradiances while the error bars are derived from the measurement precision contained in the EVE observation files. The red dashed lines are the results of the double Gaussian fitting, and the gray curves represent the primary component while the blue, the secondary. The vertical lines indicate the locations of the center of the primary (gray) and that of the secondary (blue) components. The Doppler velocities derived from the double Gaussian fitting are labeled as v1 and v2 for the primary and secondary components, respectively.
