Chemical abundances in early B-type stars. I. Sample and metal line equivalent widths.
Abstract
Equivalent widths for over 100 lines of C, N, O, Ne, Mg, Al, Si, S and Fe of 21 unevolved B-stars in the local field and nearby associations are given. The spectra cover the wavelength range 406-506 nm. Data for sharp unblended lines are accurate to 5 percent or better, for other lines the error lies between 5 and 10 percent. The tables contain equivalent widths and standard deviations for all lines measured in all 21 stars.
