CoRoT photometric measurements of asteroseismic targets need complementary
ground-based spectroscopic observations. We are using the planet-hunter HARPS
spectrograph attached to the 3.6m-ESO telescope in the framework of two
consecutive Large Programmes. We discuss its use to study line-profile
variations and we report on a specific result obtained for the Delta Sct star
HD 170699.
