VINCI/VLTI observations of L₂ Pup from 12 October 2001 to 4 November 2001 with respect to the stellar pulsation phase. The variability of the visibility is shown in the top panel, color-coded to indicate its dependency on the baseline position angle (25°−70°), while the respective uniform disk diameters are shown in the bottom panel. A folded visual light curve (open circles) is also shown for comparison in the top panel. The projected baseline length varies also by less than 1.5 m (14.66−15.98 m) with respect to the physical baseline length (16 m).
