GTC/MEGARA nuclear spectrum of NGC 2110 in the spectral region around the [O III]λλ4959, 5007 doublet. The orange line is the observed spectrum after the subtraction of the continuum and extracted with a 0.9″  ×  0.9″ aperture. The fit (dashed black line) is the sum of three Gaussian components. The dotted blue lines show each component of the fit, with lines of increasing thickness for the components with increasing velocity dispersions. The green lines are the line wavelengths.
