Hi!

This is José Soler answer:

"Without discarding the effect of imperfect density matrix
normalization, it seems to me that the most likely cause
of that small deviation from 1 is an incomplete scf
convergence, or an excessive electronic temperature."

That's how many spin-up electrons than spin-down there are in your system.

It seems to me that these figures long after comma should probably be discarded, they must be due to slightly incomplete normalization of the density. Hence, a question to the developers:

Is the above correct & how many significant figures should we keep in this number & how small is the effect of such normalization on the accuracy?

Dear Users

This is the copied line from the output file of siesta:

siesta: Total spin polarization (Qup-Qdown) =    1.000035

What does "Qup-Qdown' mean? 1.000035 is the value of unpaired electrons?
Thanks in advance!

ps. I performed calculations with Pt metal, SpinPolarized flag was set .true.
