Institutional measurement procedures covering contact geometry, reversal of electric current and magnetic field, and extraction of sheet carrier density and Hall mobility. Bulk density requires the conducting thickness.

The institutional carbon spectral line table explicitly separates vacuum and air wavelengths. Its $193.0906\mathrm{nm}$ C I line is a vacuum wavelength, while its $247.8561\mathrm{nm}$ C I line is an air wavelength. Their differing conventions matter when converting line positions into atomic energy differences.
