Map of the altitude of the scattering material in front of the plane of the sky at the distance of L₂ Pup, expressed in astronomical units. The top panel shows the map derived from the V band observations while the lower panel shows the N_R band result. The positions of the AGB star and its companion are marked with star symbols, and the location of minimum altitude is shown with a green square. The gray scale is linear between 0 and 16 AU, and the contour curves are separated by increments of 4 AU from 0 to 20 AU. The field of view is 0.60″ × 0.60″.
