A number of the traces show a very large drop in the relative energy, but little or no change in the FAT. I understand that it is generally taken that the FAT gives the biggest indication of inclusions or defects, however, I note on your web site that a low relative energy means a "weak" signal. When would I expect to get a weak signal, and could it represent an anomaly even if the FAT`s are consistent?
