VizieR Online Data Catalog: Nitrogen abundances for Be and B stars (Ahmed+, 2017)

The MiMeS survey represents an extensive spectroscopic survey of local Galactic B-type stars for detecting and classifying magnetic fields in these objects (Wade et al., 2016MNRAS.456....2W, Cat. J/MNRAS/456/2). From the MiMeS survey, two samples of stars were constructed. The first consists of 26 early-type Be stars with spectral types between B0 and B3 and luminosity classes between V and II. The second consists of 16 normal early-type B-type stars, also with spectral types between B0 and B3 and luminosity classes between V and II.

As part of the MiMeS survey, high-resolution spectra for these stars were taken with the echelle spectropolarimeter ESPaDOnS on the Cassegrain focus of the 3.6-m CFHT and the NARVAL spectropolarimeter on the Telescope Bernard Lyot. ESPaDOnS spectra have a resolving power of 80000 in the spectroscopic star-only option used for observing bright stars, and a resolving power of 68000 in the spectroscopic star + sky mode used for observations of faint stars and in polarimetric mode in which all Stokes parameters are measured. The latter mode was adopted in producing the spectra for the MiMeS survey. ESPaDOnS has a spectral coverage from 3700 to 10500Å in a single exposure, divided into 40 overlapping orders, with three gaps in the far red region of the spectrum: 9224-9234Å, 9608-9636Å and 10026-10074Å.
