Caption: Figure 3.
Fit to SDSS spectra around Hα of four galaxies, which would have wrong redshift in SDSS DR7. The green broken lines show the emissions at our fitted redshift. All of them show good fit with Hα, [N II] and [S II]. The red dashed lines show titled features at the redshift of SDSS DR7.
