Left: position–velocity diagram from our maps of ¹²CO J = 2–1 in IRAS 19125+0343 along the direction PA = −40°, corresponding to the nebula equator. The contour spacing is logarithmic: ±40, 80, 160, and 320 mJy beam⁻¹ with a maximum emission peak of 413 mJy beam⁻¹. The dashedlines show the approximate central position and systemic velocity. Right: same as in left but along the perpendicular direction PA = 50°.
