Rotation diagrams for the H₂CS peak fluxes along the major axis (PA = 45°) of the disk-like structure at 0.5′′ (left panel) and 1.0′′ (right panel) from the source center. Para transitions are shown in black and ortho transitions in blue. An ortho-to-para ratio of 2 is assumed. J = 7−6 transitions are displayed as filled symbols and J = 10−9 transitions as open symbols. The error bars include a 10% uncertainty. The best fit to all transitions is presented by the solid orange line, whereas the dashed lines show fits to only the ortho (blue) and only the para transitions (black). The corresponding rotation temperatures are listed in the top right corners.
