File containing Lyman alpha HI column densities towards O stars reliable column densities. The version that I am sending you is ASCII The file is ASCII with the different fields separated by commas. Their width is variable, so the comma should be what to use to identify them. i he fields are (1) HD/BD # (2) other name (in case there isn't one, just space and comma). Please notice that since this table was produced in a word processor there were several Greek entries for letters that now are erroneous. Just ignore them. (3) l (gal long) (4) b (gal lat) (5) Spectral type (6) V (mag) (7) B-V (mag) (8) E(B-V) (9) E(Bump) (when non-available we use "...") (10) distance (pc) (11) z (pc from Galactic plane) (12) log NH_total (observed) (13) error in log (14) [c1] (used to estimate stellar NH, when non-available we use "...") (15) log NH_stellar (when non-available we use "...") (16) log NH_interstellar (17) reference (list in the paper text)
