Correct me if I'm wrong, but I believe you are saying that you opened 
the case.scf file in a text editor or did a "grep -e :MMTOT -e :MMI -e 
:MMINT *.scf", then got the values from the last ITERATION.  The :MMIn 
being the total spin magnetic moment [1,2].

The :MMIn for the V atoms having 0.05 μB or -0.05 μB. The :MMTOT, :MMIn 
for the S atoms, and :MMINT are 0 μB.

Thus, you have some like:

0 (for :MMTOT) = [0.05 μB * multiplicity + -0.05 μB * multiplicity] (for 
:MMIn of V atoms; this showing the canceling moments of an AFM 
configuration [3]) + 0 (for :MMIn of S atoms) + 0 (for :MMINT)

>   what was your charge convergence criterion ?

In addition to needing know what was used for -cc, maybe they would also 
need to know how :MMIn behaved in the last several iterations like in 
the posts [4,5].
