Caption: Figure 3.

Flowchart of the fitting process when x1 > x0. The lower inset illustrates the fitting process for row x0 + 1. For each spectrum (spaxel N) in row x0 + 1, the initial guess for the fitting is determined by the result with the minimum ﹩{\chi }_{{\rm{red}}}^{2}﹩ among the k neighboring spectra(spaxel 1, 2, 3…k) from row x0.
