Patches at 0° < |b| < 5° (top row), 5° < |b| < 30° (middle row), and 30° < |b| < 90° (bottom row) latitude intervals. They represent the maps with all the emissions, the CMB label, the neural network output, and the residual map computed as the difference between the second and the third column patches from left to right. The frequency is 217 GHz, and their temperature (in µK_CMB) is shown in the right vertical bars. The x and y labels are the pixel coordinates for each 256 × 256 patch.
