Observed CN spectra (red), extracted from the outer region of the disk (>210 au), with the Gaussian fits (green). Top and bottom panels: HF structure extracted from the western and eastern sides of the disk, respectively. Cyan lines in the observed spectra mark the brightest HF components and have been scaled to match the peak intensity in the B component of the observed spectrum. The dashed blue line represents the systemic velocity of the system (~3.7 km s⁻¹). These data can be converted to Jy km s⁻¹ by using the unit conversion factor of ~55 K.
