Inversion results for the three observational setups. First row: meridional flow measurements with both hemispheres of the Sun being observed. Second row: same as top, but with two patches for each hemisphere observed on the front and on the farside of the Sun. Third row: same as top but with observations of two patches, one on the northern, the other on the southern hemisphere. The red lines indicate the averaged flow amplitudes below the observed patches on the northern and southern hemispheres, as taken from the input model. Horizontal error bars represent the quantile width of the averaging kernels.
