WebIt is clear that using CRYSTAL09 or CRYSTAL14 has no effect on values used for this work. It is also evident that using 5 points on the deformation gradient instead of 3 has no effect beyond numerical noise. The use of a significantly difference basis set has only a small effect that would always be expected.
