 In convergence delta factor calculation, the GS configurations from Cottiner's paper are used.
 To have a uniform sence of precision through looking at delta factor, the value is defined as delta factor per atom.
 However, since it is hard to define delta per/atom for oxides, ACWF does not use per/atom value to represent results.
-To compatible with it, the precision verification also use the structure delta.
+It uses the nu factor which was defined in the ACWF paper.
+
+For the oxides, it needs oxygen pseudopotential first, same as nitrides.
+The verification needs to run for all know oxygen/nitrigen pseudopotentials filst. However, the cutoffs of them are not known and the cutoffs are input for the precision measure.
+So the very first run is the convergence test on all oxygen/nitrigen pseudopotentials.
+Once the recommended cutoffs are known, the precision measure can be run for all oxygen/nitrigen elements.
