Hi. I'm having a problem with running dm with ncs averaging. I have a trimer and am inputting in 3 domains using euler angles calculated using the profess: Domain 1 should be the identity matrix, if I'm understanding things correctly, so I put 0.0 0.0 0.0 for the three angles and 0.0 0.0 0.0 f

Apologies for the late posting (been away). Interesting question from James and an interesting answer from Ian! There should be a radiation pressure effect here resulting in a transfer of energy and momentum to the sample. The effect is very small (the term includes flux density divided by spee
