[Discus-talk] Setting variables in DISCUS PDF module

[Kris H. <kri...@mc...>]

Hi,

As a first exercise, I'm attempting to reproduce an RMC fit of a neutron
PDF from a published article.  I've gotten close but don't know how to
change two parameters:

*Neutron scattering wavelength:* How do I read out (and change if needed)
these values?  The command "show" produces a section called "Weights for
pdf calculations", but I don't see how to connect this to values of b_i in
the equation given in the manual for G(r).

*Scaling experimental data:*  My initial simulations look close, but I need
to scale the entire simulation smaller to about 80%  to match the
experimental data. I'm guessing it's theoretically OK to do this? The
manual lists a variable pdf_scal[i] but I can't seem to figure out the
syntax to set it. I guess scaling the value of the average scattering
power, <b>, would do the same thing, but I'm not sure how to do that either.

thanks for any help,
Kris
