Image Details
Caption: Figure 9.
Normalized cross-correlation, ρNX, of the four simulated images compared before and after convolution with a circular Gaussian kernel with FWHM α. The vertical dashed line shows the nominal diffraction-limited resolution of the EHT (see Table 1). For each source, we invert these curves to obtain from a given ρNX an equivalent blurring kernel size α. The Top Set reconstructions are defined as those with this α smaller than the nominal EHT resolution.
