| Abstract: |
The secondary in CVs is usually detected by correlation of the spectrum with that of a red dwarf template, to produce a radial velocity curve. This method has demonstrated its power, but has limits in case of noisy spectra, as in faint secondaries. To circumvent this difficulty, a method of co-adding spectra, called skew mapping, has been proposed in the past. This paper explores the capabilities of skew mapping in determining the amplitude of the radial velocity for faint secondaries. We record our appreciation to Dr T. R. Marsh for advice on his ``molly'' code. Thanks are due to the observers and data reducers (D. H. P. Jones, N. A. Hawkins, J. Thorstensen, and J. S. Martin). |
