Channel degradation over time. From top to bottom: Channel 94 Å (blue), 131 Å (yellow), 171Å (green), 193 Å (red), 211 Å (purple), 304 Å (brown), and 335 Å (magenta). The solid black (gray) curve is the degradation profile of AIA calibration release V9 (V8). The gray shaded area correspond to the error (10% earlier than May 2014 and 28% error later) of the degradation curve V9. The colored shaded areas are the standard deviation of the CNN models. The vertical dashed black line is the last available observation from EVE MEGS-A data, and the vertical dashed gray line is the last training date.
