Spectra of the D1 region covering the wavelengths nearby the Hγ(left panel) and the Hα(right panel) lines, including the best-fits of the observed lines. The left panel also includes a tentative detection of the [OIII]λ4363 line. An artificial 5σ signal at the expected wavelength of the [O III]λ4363 and of the [NII]λ6585 lines is shown as a blue-dashed line.
