High-quality slitless radial velocities of extragalactic PNs with Subaru and FOCAS
Published online by Cambridge University Press: 15 December 2006
Abstract
We describe the implementation and accuracy of slitless radial velocity measurements of extragalactic PNs with Subaru and the FOCAS spectrograph. As a first application of the method, we have extended a previous study of PNs in NGC 4697 to larger angular distances from its center, failing again to find evidence of dark matter in this elliptical galaxy.
