Thank you all very much for the immediate
help.
One more question, may I???
What can the minimum kmax be?
I think it can be about 8 according to
Scott.
If I use kmin=2, can it be 7 or 6? The reason why
I ask this is that when I plot R space with my sample, which has been reduced
and needs to be confirmed if there is any metal cluster, the metal
peak shows at kmax=8, but it disappears at kmax=6 or 7. At kmax=10, it is
hard to tell because the spectrum is very noisy (it shows split peak). When
there are extremely small metal clusters (even at CN=0.6), I can see a
distinct metal peak that does not change no matter what k range and weight I
use. I wonder any further advice can be suggested.
Thank you for your help in advance.
