High-quality slitless radial velocities of extragalactic PNs with Subaru and FOCAS
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.
