Intensity (contours) and velocity (color-scale) integrated maps of DCO⁺ ACA observations. Note the 10 times larger scale of this figure compared with Fig. 1. The positions of VLA1623A, B and W are marked with a square, triangle and circle, respectively. The size of the filled square shows the size of the C¹⁸O disk. The red and blue lines indicate the outflow direction while the gray line shows the mayor axis of the disk plane. The black ellipse shows the synthesized beam. Contours are in steps of −3, 3, 5, 7, 10, 15 and 17σ with σ = 220 mJy beam^-1 km s^-1.
