MRS [O III] 5008 Å and Hα emission line fits. The left and right panels show the one-component Gaussian fits, together with the fit residuals, for the [O III] 5008 Å and Hα emission lines, respectively. The continuous black line shows the 1D extracted MRS spectrum. The gray area shows the ±1σ uncertainty calculated from the standard deviation of the local background. The green dashed line shows the one-component Gaussian function that fits the spectra best. The black vertical dashed line is the wavelength at the peak of each emission line considering a redshift of 10.602. The ${\chi }_{\nu }^2$ for each emission line fit calculated in the velocity range, −500 < v [km s⁻¹] < 500, is included.
