The mean (circles) and median (diamonds) of the gap magnitude. The shaded areas represent the local variations in the gap magnitudes and fillings by depicting the histograms. The green dashed lines in a show the expectation of a gap size proportional to T c , with a proportionality constant either chosen to match the OPT35K data point, or determined by weakly coupled d -wave BCS theory. The doping levels were calculated using the Presland formula for the superconducting samples, and using the antinodal band shift measured by photoemission for the OD0K sample.
