v36 v37 36 36 37 37 38 Continuing through to the output stack, the heavy mottling from before is gone, with an expected smooth noise pattern with slight bumps where the number of input frames is smaller . Plotting up the image and variance profiles again for this new stack (scaled by a factor of 10 to not mask out the profiles from the old stack) shows that the image and variance frame now resemble each other, so the excess detections previously found on this stack should not be an issue.38 Continuing through to the output stack, the heavy mottling from before is gone, with an expected smooth noise pattern with slight bumps where the number of input frames is smaller (top panels, new unconvolved stack and variance; bottom panels, old unconvolved stack and variance).
