Notes. We show the properties of each data-set, including the references to previously published works, observation ID, detector (I = ACIS-I, S = ACIS-S), observation mode (F = FAINT, V = VERYFAINT), and exposure time. The best-fit parameters T(z_o) and Z_Fe(z_o) are obtained with the redshift frozen to the optical value z_o. Temperature and metal abundance refer to the global fit to the spectrum extracted within the radius R_ext, and therefore represents an average value whenever a temperature or a metallicity gradient is present. The last column refers to the Galactic Hydrogen column density as measured by Wilms et al. (2000).
