Dear FullProf Users,
I'm a PhD student learning the use of FullProf for
Riteveld refinement; I read the manual, but I have still some
doubts:
1) BKpos: it's the origin of polynomial
function for background: where do I derive it ? I found an example about a
refinement on HRPD (ISIS) from where my data too come, and BKpos = 45000.0; can
I use this value even if I change background type ?
2) Iabscor: it's the absorption correction for TOF
data (it's 2 for cylindrical samples); is it always necessary ?
3) Tmin - Step - Tmax : what's the meaning of Step
in a TOF measurement? In the example it's 2.3125, where does it come this value
from?
4) in the section of profile function, and in
particular where there are the parameters of the relation between TOF and d,
what is the meaning of the codes for Zero, Dtt1, and Dtt2 ?
Thanks in advance, and excuse me for the triviality
of questions!
