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.
| Meridian observations made with the Carlsberg Automatic Meridian Circle at Brorfelde (Copenhagen University Observatory) 1981-1982
The 7-inch transit circle instrument with which the present position andmagnitude catalog for 1577 stars with visual magnitudes greater than11.0 was obtained had been equipped with a photoelectric moving slitmicrometer and a minicomputer to control the entire observationalprocess. Positions are reduced relative to the FK4 system for each nightover the whole meridian rather than the usual narrow zones. Thepositions of the FK4 stars used in the least squares solution are alsogiven in the catalog.
