Integrated intensity map for the H¹³CO⁺ J = 3 − 2 transition (color scale) toward IRAS2A. The DCO⁺ J = 2 − 1 transition is overlaid in pink contours. Contours are shown in steps of 1σ starting from a 3σ level (15 mJy beam⁻¹ km s⁻¹). The beams are depicted in the bottom left corner. The position of the continuum peak is indicated by a white cross and the outflow axes by red and blue arrows. The length of the arrows is the same as in Fig. 2 to compare the scales. The solid white contour represents the CO snowline radius predicted by the chemical model for the Kristensen et al. (2012) temperature profile (~2000 AU).
