Deprojected and azimuthally averaged 284 GHz continuum intensity and integrated N₂H⁺ 3 − 2 line intensity radial profiles. Top row: continuum intensity profiles normalized to peak values. Bottom row: radial profiles of integrated line intensity. The color shades show the standard deviation in pixel intensities calculated at each annulus. Adopted distances are listed in Table 1, and adopted position angles and inclinations are listed in Table 3. The black bars in each panel represent the restoring beam major axes. Note the distinct N₂H⁺ morphologies in the three leftmost disks (a narrow ring followed by a low-level plateau), and the three rightmost disks (a broad torus more extended than the continuum disk).
