To check the transferability of generated pseudopotentials, a useful measure is to compare logarithmic derivatives of wave functions [16]. If the logarithmic derivative of pseudopotential is comparable to that by the all electron calculation through a wide range of energy, then the pseudopotential would possess a good transferability. In Fig. 4 shows the logarithmic derivatives in a carbon atom, indicating a good transferability of the pseudopotential. The keywords concerned to the calculations of the logarithmic derivative are as follows:

**log.deri.RadF.calc**When the logarithmic derivatives are calculated, then ON, otherwise, OFF.

**log.deri.MinE**The lower bound of energy (Hartree) used in the calculation of logarithmic derivatives of radial wave functions.

**log.deri.MaxE**The upper bound of energy (Hartree) used in the calculation of logarithmic derivatives of radial wave functions.

**log.deri.R**Radius at which the logarithmic derivatives of radial wave functions are evaluated.
