The hydrogen equivalent column densities were obtained from the Exploring the X-ray Transient and variable Sky project ({\\sc EXTraS}) which provides equivalent $N_{\\rm H}$ values from X-ray spectral fits of observations within the {\\it XMM-Newton} Data Release. {\\sc EXTraS} include multiple fits for each source, allowing an accurate determination of the equivalent column densities, which depends on the continuum modeling of the spectra.
