I have couple of questions.
1. I found in many tutorials that the value of amp should lie between 0.7
and 1. But when I refined it goes to 0.15, what's wrong with it.
2. The value of sigma2. Some time at high k, value, it turns to negative
but small. What I suppose to do?
3. If I need to know the behavior of octahedra distortion with temperature,
and it is lies within the first shell. So what is the need of higher shell
Thanks in advance
