NXS as a function of the light curve duration in the rest frame, Δtrest. Black dots represent individual NXS values. Blue circles are ensemble averages in bins of Δtrest. The solid blue line shows a linear least-squares fit to the logarithms of the binned values with slope a = 0.196 ± 0.040. The Pearson correlation coefficient is r = 0.84, with null probability P( >| r | ) = 0.008.
