The covering fraction $f$ and the hydrogen column density, $N_{\rm H}^{\rm pow}$, are allowed to vary to explain the spectral changes in the spectra. Uncertainties are given at a 90\% confidence level. We also indicate the significance of the change of $N_{\rm H}^{\rm pow}$ and $f$ between shallow and deep-dipping spectra. \end{list} \end{table}
