Overlay of the CME (red cross) and ray (blue cross) central longitudes and latitudes determined from the 3D modeling of Sect. 3 on an MDI magnetogram taken during 1 April 2008, when the host AR (i.e., NOAA 1098) was close to the central meridian as viewed from SOHO. The dashed blue box has a length/height equal to the depth/thickness of the WL ray as determined from our 3D modeling. Its orientation cannot be determined from our modeling (see the discussion of Sect. 3).
