A list of data for the broadening by neutral hydrogen collisions of many astrophysically important spectral lines, which has been incorporated into the Vienna Atomic Line Database (VALD), is presented. Data for lines of neutral atoms are interpolated from the tabulated data of Anstee & O'Mara (1995), Barklem & O'Mara (1997), and Barklem et al. (1998). Data for lines of singly ionised atoms are compiled from the calculations by Barklem & O'Mara (1998, 2000). The list at present contains data for 4891 lines between 2300 and 13000 Å of elements from Li to Ni. We examine the statistical impact of the new theory by comparison with the previously available data. We also demonstrate the direct effect on spectral synthesis calculations.
Barklem et al. (Wed,) studied this question.
