Notes. (1) Name of the foreground galaxy and the background source. (2) Peak flux of the continuum source. (3) Optical-depth rms uncertainty in absorption spectra. (4) Fraction of CNM mass compared to total H I mass. (5) Density-weighted mean spin temperature. (6) Phase of the H I. (7) Spin temperature (for CNM only). (8) Maximum kinetic temperature. (9) Peak optical depth (for CNM) or peak brightness temperature (for WNM). (10) Velocity of the peak optical depth or brightness temperature. (11) FWHM velocity width. (12) H I column density of this component.
