Vulnerability curves (VCs) obtained on the basis of binarization of A*T2 product maps. The matrix size of the images was varied (32 × 32, 64 × 64, and 128 × 128, resulting in pixel sizes of 0.59 × 0.59, 0.30 × 0.30 and 0.15 × 0.15 mm for spruce and 0.72 × 0.72, 0.36 × 0.36 and 0.18 × 0.18 mm for beech), while field of view was held constant. A subset of the binarization masks that the VC’s are based on is shown, together with the corresponding water potentials (WP), in (a) for spruce and (b) beech. The resulting VCs are shown in panels (c, e, g) for spruce; and in panels (d, f, h) for beech
