Zoom onto the signal found at the position of the visual detection N1. The top boxes show the last image taken before the detection (left), the image containing the detection (middle), and the image taken after the registered detection (right), while the bottom boxes correspond to the difference images obtained by subtracting the reference frame from each of the science images shown at the top. Each box is about 6″ × 6″ in size, and the color scale is logarithmic.
