SAMPol Stokes I map at 2.30 μm (February 2013) reconstructed with the BSMEM algorithm. Two clumpy structures emerge at ~65 mas in the east–west direction at levels above 2% of the peak intensity with a possible extension to the northeast. The central star (L2 Pup) is unresolved at this wavelength (θ ≤ 30 mas, ≥ 50% peak intensity), but the surrounding envelope (θ ~ 50 mas) is non-spherical. Contour levels are at 1, 2, 5, 10, 20, 50, and 80% of the peak intensity. North is up and east is on the right.
