Line to continuum ratio maps of the [O I] λ6300, [S II] λ6731 and [N II] λ6583 channel maps shown in Figs. C.1 and C.2, before continuum subtraction and deconvolution. A sector of the ALMA 1.3 mm dust continuum disk image is shown in white contours. Intrinsic line emission appears bright in these images, whereas scattered light is represented by a constant ratio close to unity. The red arrow delineates the disk PA and radius from Huang et al. (2018) (121° ± 5°, 63 ± 1 au) and the green dashed line represents the jet PA measured here (213° ± 2°).
