Examples of spectra from two component fit but with poor spectra and single component fit. Top panel: An example of the spectra with the single component fit (ID 8813) and FWHM< 800 km s⁻¹. Bottom panel: An example of the spectra with two component fit (ID 5185) but whose flux-to-flux error ratio is less than 2.5. These sources were excluded from our final candidates with outflows because the additional broad component is not significant. In both panels, the red line indicates the total fit. The vertical dotted lines indicate the peaks at 4862.68, 4960.30, and 5008.24 for H_β and [OIII] rest-frame wavelength.
