Residuals of the DCO⁺ radial profile (as shown in Fig. 3) by subtracting first the DCN radial profile and then the N₂D⁺ radial profile. The shadowed color area represents 1σ errors, where σ is the standard deviation in one elliptical annulus. The black dashed line corresponds to the location of the CO snowline (90 AU).
