Projected radius measured at a surface brightness of ∼10⁻¹⁷ erg s⁻² cm⁻¹ arcsec⁻² for the stellar continuum versus the ionized gas. The dashed black line corresponds to the one-to-one size relation. The sources are color-coded as follows: orange left-pointing triangles for extended rotating disks, orange circles for compact rotating disks, and blue right-arrows for systems with filamentary structures. We remark that the extension of the filamentary systems is likely a lower limit due to the projection effects and a sensitivity threshold.
