Table 2 Estimates of \({\mathrm{MSP}} _{j}\) for \(j=9,\ldots ,12\). The error is the standard deviation of the mean of the estimates from the individual images. The position \(\varrho _{\mathrm{max}}\) of the maximum and the norm \(\|\hat{h}_{j}\|\) of the transfer function \(\hat{h}_{j}(\xi )\) are included to facilitate interpretation
