OH line emission maps of IRAS 01298−0744 from VLBA observation. The top left image shows the integrated channel image of OH emission encompassing velocities from 40 554 to 40 937 km s⁻¹. The other three images depict channel images at three peak velocities, each with a velocity width of approximately 3.8 km s⁻¹, highlighting the brightest components A, B, C, and D. Their respective coordinates are as follows: A: 01 32 21.415, −07 29 08.346; B: 01 32 21.414, −07 29 08.336; C: 01 32 21.414, −07 29 08.348; D: 01 32 21.415, and −07 29 08.344. The red and black contours represent the OH line emission (40 554–40 937 km s⁻¹), with contour levels of 0.72 mJy beam⁻¹ × (1, 2, 4, 8), and the radio continuum emission, with contour levels of 0.06 mJy beam⁻¹ × (1, 2), respectively. The colour bar on the right of each figure shows the OH line flux densities at each pixel in Jy beam⁻¹. The synthesised beam of each channel image is shown in the bottom left corner.
