RemarksR=0.031000 : RVP TEM =295 : XDP
At least one temperature factor is implausible or meaningless but agrees with the value given in the paper.
Difference between the formula calculated from the PARM record and the FORM record tolerable.
Unrealistic negative temperature factors (Ni, Mg, V: B=-0.6(1), O: B=-0.2(1)) in the paper. Replaced by 0.01.
