Integrated intensity map for the H¹³CO⁺ J = 3 − 2 transition (color scale) toward IRAS2A. The 1.2 mm continuum is overlaid in white contours (top panel) and the HO 3_1,3 − 2_2,0 transition in blue contours (middle panel). The continuum contours are 1.8 (1σ) × [3, 10, 25, 50, 75] mJy beam⁻¹, and the HO contours are 9.8 (1σ) × [3, 8, 15, 25, 35] 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 black cross (the close binaryis unresolved in these data) and the outflow axes by red and blue arrows. The integrated intensities along the dashed white line are shown in the bottom panel, normalized to their maximum value. The zero flux level and source position are indicated by dotted lines.
