Hi,
After a couple of chat with Leo Spyracopoulos, I understand better the
link between s / rad ans s in spectral density mapping.
Leo started with :
"The results from the notebook should not be multiplied by 2 pi.
Finally, by definition, a radian is a dimensionless quantity with no
physical unit associated with it, so there is no error in the 2006
paper. However, it is probably best to quote the spectral densities
using just units of time."
He also told me about some papers writing their tauc values in ns / rad
instead of ns, but keeping the same value (no scaling with 2 pi).
Leo ended saying that :
"When Jeff Peng wrote the paper he felt it was important to quote the
spectral density values in s/rad. If you look at his spectral density
values and just use ns instead of ns/rad, you get the right values.
However, I think that the spectral densities should really only be
quoted in s (or ns)."
I thus think that everything is now fine with jw_mapping within relax.
The output are in s, which is fine and consistent with SI units.
Finally, I think that every place with ' s / rad ' should be changed for
's'.
Cheers !
