Caption: Figure A3.
Light curves of reference pixels compared with the Sgr A* pixel. Gray curves in each panel (Channels 1, 2, 3, and 4 in panels (A), (B), (C), and (D), respectively) show the reference-pixel light curves after removing the linear slope but without subtracting each pixel's median value. Colored lines show the same for the Sgr A* pixel.
