-Fading procedure
$\bullet$ At first, the S^D and S^? differ along at least one ____________________________ dimension,
$\bullet$ as well as the ____________________________dimensions.
$\bullet$ Then the difference between the S^D and S^? is reduced along all but the ____________________________ dimensions,
$\bullet$ until the S^D and S^? differ along only those ____________________________dimensions.
