Candidate marked by algorithm in KIC 8462852. The white pixel in the middle is a NaN value, indicating the pixel contained more than the 65,536 maximum allowed value by HIRES readout electronics. See Figure 4 and the text for an explanation of the panels. The distribution of photons in both the spatial (up-down) and wavelength directions are narrower than the point-spread function in those two directions, indicating that a high energy particle directly deposited large amounts of energy on the heavily saturated single pixel (with the NaN value) which spilled into neighboring pixels. Note the absence of wings in the spatial direction that should extend 3–5 pixels from the center of the “line” if it were caused by light actually passing through the HIRES spectrometer (See Figure 7).
