Abstract:

The file (tableE.dat) in this directory constitute the on-line material
(electronic table) for the paper "Photospheric silicon abundances of
upper main-sequence stars derived from Si II 6347/6371 doublet lines 
(Y. Takeda)", which includes the data of fundamental stellar parameters 
and the results of abundance analysis for the 120 program stars.

Description: "tableE.dat"
--------------------------------------------------------------------------
This file comprises 120 lines of data, each corresponding to the targets 
of this study, respectively. Included data in each line are: fundamental 
stellar data (e.g., catalogue number, spectral type, atmospheric parameters, 
photometric data, parallax, projected rotational velocity, etc.), 
and the results of abundance analysis (non-LTE Si abundances derived from
6340--6380A fitting and the equivalent widths of Si II 6347/6371 lines inversely 
computed from fitting-based solutions along with the non-LTE corrections),
where two kinds of abundances are presented corresponding to different choices 
of microturbulence (standard value based on an analytical Teff-dependent 
formula and the directly determined value by spectrum refitting).
