Notes. Offset b from Fig. 6 for pixels where both lines (line x and line y) are significantly detected. We define b = mean(log₁₀(y/x)) with x and y referring to the values on the x and y axes from line x and line y, respectively. We calculate b for pixels where both line x and line y are significantly detected in the full FoV (3), the central 1 kpc (4), and the remaining disk excluding the central 1 kpc (5). We add the significance of the difference of b calculated in the center compared to the disk. We define it as $σ_{cen - disk} = \frac{b_{cen} - b_{disk}}{\sqrt{Δ b_{cen}^{2} + Δ b_{disk}^{2}}}$ $\sigma_{\mathrm{cen-disk}} = \frac{b_{\mathrm{cen}} - b_{\mathrm{disk}}}{\sqrt{\Delta b_{\mathrm{cen}}^2 + \Delta b_{\mathrm{disk}}^2}}$ . Values including HNCO(5-4) should be taken with caution, as this line is only significantly detected in very few pixels in the FoV.
