Blueshiſted and redshiſted integrated emission of ¹²CO (2–1) toward the IRAS 15398-3359 region. The blueshiſted and redshiſted emission were integrated over the velocity ranges from 2.3 to 4.7 km s⁻¹ and from 6.2 to 7.4 km s⁻¹. Blueshiſted and redshiſted contours are represented at 10, 20, 30, 40, 50, 60, 100, and 150 times the rms of 0.l5 mJy beam⁻¹ km s⁻¹ and 0.1 mJy beam⁻¹ km s⁻¹, respectively. The stars indicate the position of IRAS 15398-3359 and 2MASS 15430576-3410004. The synthesized beam (7.′′7×4.′′2, PA=86^◦) is represented by the black ellipse in the bottom left corner.
