WebJul 4, 2024 · FWHM 90º was considered as an indicator of the disk’s definition at 90°. As already mentioned, DBT presents a lower quality in z than in xy and this is exposed in the spreading of structures of high intensity in z (such as these disks). Although the disks have a thickness of 1.0 mm, the observed values will be higher. WebNov 16, 2015 · The first plot is between a low energy range, the second between a significantly higher energy range. It is clear that the FWHMs (Full Width Half Maxima) of the peaks in the spectrum increase with energy. …
