Three lines in each figure corresponding to three horizontal cross-sections from images in Fig. 4. The units on the y-axis are dimensionless [Jy2Jy2]. στ is the maximum characteristic error correlation length. In decreasing intensity, they correspond to m = 0″, m = 4″, and m = 8″. The dashed lines correspond to the variance measured with 2000 realisations for each pixel, while the solid line correspondsto the predicted value at that pixel. There are 31 pixels. We do not show cross-sections for negative m due to image symmetry about the origin.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
