Example of two-component NBURSTS fitting for the region with a₁ and b galaxies. The black line shows the observed spectrum in the spaxel, and blue is the total best-fitting model. Red and green lines are stellar components of a₁ and b galaxies, and the orange line is the emission line component. Black dots are residuals, and the grey line shows the spectrum errors. The shaded regions were excluded from fitting, and the purple line is the multiplicative continuum. The growing trend from the blue to the red spectrum part of the multiplicative continuum is a correction for the extinction.
