A radial-velocity survey of the Hyades Photoelectric radial-velocity measurements, obtained with external erroras small as 0.1 km/s using the 200-inch Hale telescope at PalomarObservatory during the period 1971-1986, are reported for over 400candidate members (with V magnitude between 6 and 14) of the Hyadescluster. The history of Hyades observations is recalled; the Palomarinstrumentation and observing program are described; the data-reductionand standardization procedures are discussed in detail; and the data arepresented in extensive tables and graphs. About 200 of the stars areclassified as cluster members, including 60 spectroscopic binaries.
| Photometry of possible members of the Hyades cluster. V Photoelectric BVRI observations have been obtained for 36 starssuspected of being members of the Hyades cluster, mostly on the basis ofthe proper-motion survey by Artyukhina and Kholopov. Most of the starsare in the outer regions of the cluster and, on the basis of thephotometry, only six of the 36 stars appear to be possible or probablemembers. This illustrates the difficulty of identifying outlying clustermembers on the basis of proper-motion measures alone.
