Continuum decomposition for six different regions. The axes are flux density [10^-18 W m^-2μm^-1] versus wavelength [μm]. The components are: red curve: hot dust component; Yellow curve: power-law component; full blue curve: total stellar component; lined blue curve: M0III star; Line-dot blue curve: K3III star; triple-dot-lined blue curve: G5III star. The combined components curve is in green and the original input spectrum is in black. The dotted black curve around zero is the residual of spectrum minus combined curve. We note that the emission lines at λ2.223 μm and λ2.247 μm were masked.
