For damped absorbers, the Lorentzian component of the Voigt profile results in pronounced damping wings, allowing precise determination of $N_{{\rm H}\,{\sc \rm I}}$ down to the sub-DLA definition at high-resolution. The neutral hydrogen column density measurements of these absorbers are determined by fitting a Voigt profile to the Ly$\alpha$ absorption line. The fits were performed using the $\chi^2$ minimization routine `FITLYMAN` package in `MIDAS` [@fontana]. Laboratory wavelengths and oscillator strengths from @morton2003 were used. The global fit returns the best fit parameters for central wavelength, column density, and Doppler turbulent broadening, as well as errors on each quantity. The central redshift was left as a free parameter except when no satisfactory fit could be found in which case the strongest component of the metal line was chosen as central redshift. The Doppler turbulent parameter $b$-value was usually left as a free parameter and sometimes fixed because of low signal-to-noise or multiple DLAs at 30 km s$^{-1}$ (for DLAs) or $20$ km s$^{-1}$ (for sub-DLAs). The $N_{{\rm H}\,{\sc \rm I}}$ fit is performed using the higher members of the Lyman series, in addition to Ly$\alpha$, where these are available.
