Transmission map for the three nulled outputs for a VLTI 4-UT aperture geometry over a ±15 mas field of view. A five pointed star marks the location of the center of the field, where the rejection by the nuller is optimal. The three maps share the same colorbar, with a transmission that ranges from zero on the null to close to 100% (4 F_T) for a few places in the field whose positions are dictated by the geometry of the interferometric array.
