Notes. Radial locations and azimuths given in au and degrees, respectively, are referred to the disc reference frame. Radial separations and position angles given in arc-seconds and degrees are referred to the sky plane. The origin of sky coordinates is offset from the disc centre according to the model (xc, yc) values reported in Tables A.1A.5 for each disc. The disc orientation parameters used to convert coordinates from one reference system to the other are also summarised in said tables.(*) Value converted from sky coordinates reported in the referenced work to disc coordinates using orientation parameters retrieved in this work.
