The standard deviation for the jackknife and debiased jackknife estimates of the covariance σJK, for NJK = 74, are compared to the sample covariance. The lines and error bars represent the mean and spread across ten realisations. See Fig. A.2 for details on the subplot layout. Debiasing removes the bias towards high diagonal components in the jackknife covariance.
