Investigations of CP and Normal Stars with Coadded Dominion Astrophysical Observatory Spectrograms
Published online by Cambridge University Press: 12 April 2016
Abstract
We describe the procedures developed at the Dominion Astrophysical Observatory to coadd high dispersion coude spectrograms and thus increase the signal-to-noise ratio in photographic data. These techniques can yield low noise spectra over a considerable wavelength range. Preliminary results of the analyses of such coadditions are shown to demonstrate the power of these procedures.
