Figure 24From: The black hole accretion code Matrix of image differences \(\pmb{\mathcal{D}_{i,j}}\) . Matrix of image differences \(\mathcal{D}_{i,j}\) of the four panels in Figure 23. Upper diagonal panels are greyscale differences. Lower diagonal panels are identical to corresponding upper diagonal panels but with differences illustrated with RGB pixel values. Black panels correspond to \(\mathcal{D}_{i,i}\), i.e., trivially the difference between an image and itself.Back to article page
