VizieR Online Data Catalog: sdOB star Feige 46 spectrum (Latour+, 2019)
Abstract
The star was observed multiple times with the 2.3m Bok telescope at Steward Observatory on Kitt Peak between 2004 and 2011. The observations were obtained with the B&C spectrograph using the 400mm-1 grating in first order and a 2.5-arcsec slit, resulting in a wide wavelength coverage (3620-6900Å) and a rather low resolution of 8.7Å. Our final spectrum with high S/N was constructed from five median-filtered individual spectra that were first cross-correlated to correct for possible variations in radial velocity.
