[3dem] spatial coherence on a Talos Arctica

[Morgan, David Gene]

Hi,

Has anyone thought about or even measured the spatial coherence of a Talos Arctica at different spot sizes?  We see something odd when changing spot size that could be anything from operator error to spatial coherence to issues with our FEG...
