Several flux-constant line-blanketed model stellar atmospheres were computed for Vega. The stellar effective temperature was found to be 9650 K by comparisons of observed and computed absolute fluxes at 5556 A and of relative absolute fluxes between 3300 and 10800 A. The Balmer line profiles give log g = 3.9 + or - 0.2, consistent with the result from the Balmer jump and with that found from the radius and (estimated) mass. The TI II and Fe II curves of growth give abundances of log N(Ti) = 4.7 + or - 0.3 and log N(Fe) = 7.1 + or - 0.3 on the scale log N(H) = 12.0.
