 | LSUBROT | LSUBROT must be set to False (the VASP default). |
 | MAGMOM | While any initial magnetic moments are allowed, the final total magnetic moment for any given atom must be less than 5 $\mu_B$ (Bohr magnetons) (except for elements Gd and Eu, which must be less than 10 $\mu_B$). This simply serves as a filter for erroneous data. |
 | ML_LMFF | ML_LMFF must be set to False (the VASP default). |
-| NG{X,Y,Z} | The values for NGX/NGY/NGZ must be at least 0.9 times the default value for the respective parameter generated by VASP. If the user simply does not specify these parameters, the calculation should be compatible with MP data. |
-| NGF{X,Y,Z} | The values for NGFX/NGFY/NGFZ must be at least 0.9 times the default value for the respective parameter generated by VASP. If the user simply does not specify these parameters, the calculation should be compatible with MP data. |
+| NGX / NGY / NGZ | The values for NGX/NGY/NGZ must be at least 0.9 times the default value for the respective parameter generated by VASP. If the user simply does not specify these parameters, the calculation should be compatible with MP data. |
+| NGFX / NGFY / NGFZ | The values for NGFX/NGFY/NGFZ must be at least 0.9 times the default value for the respective parameter generated by VASP. If the user simply does not specify these parameters, the calculation should be compatible with MP data. |
 | NLSPLINE | NLSPLINE should be set to False (the VASP default), unless explicitly specified by the relevant MP input set. |
 | NBANDS | NBANDS must be greater than the value $\mathrm{ceil}(\mathrm{NELECT}/2) + 1 $(minimum allowable number of bands to avoid degeneracy) and less than 4 times (minimum allowable number of bands to avoid degeneracy). For high-throughput calculations, it is generally recommended to not set this parameter directly. See https://github.com/materialsproject/custodian/issues/224 for more information. |
 | NELECT | NELECT must not be changed from the default value VASP would use for the particular structure and pseudopotentials calculated. The easiest way to ensure that NELECT is compliant with MP data is to simply not specify NELECT in the INCAR file. |
