Radial temperature profiles derived from the rotation diagrams including all transitions (first column), only transitions with E_up < 200 K (second column), only para transitions (third column), or only ortho transitions (fourth column). Top row: radial profiles along the major axis of the disk-like structure (PA = 45°), bottom row: profiles along the minor axis. The shaded area represents the 1σ uncertainty. The vertical bar in the right panels shows a typical 3σ error for theinner 100 AU and the horizontal bar marks the beam size.
