Normalised cylindrical window functions at k_∥ = 0.4 h Mpc⁻¹ for closure phases (top row) and visibilities (bottom row). Each column shows the window functions for a different triad: a linear east-west triad with two 14.6 m baselines, an equilateral 29.2 m triad, and a scalene triad with one short baseline (29.2 m) and two long baselines (105.3 m and 116.8 m) (cf. Figure 6). For visualisation purposes, the bottom row shows the sum of the visibility window functions of the three triad baselines. The contour lines are at the levels of 10⁻⁴, 10⁻⁶, and 10⁻⁸. The shaded regions in the bottom right corners indicate the standard wedge region.
