“…Four binaries, SLR 1, COO 197,R 283,and HJ 4539 show significant offsets between the predicted and observed positions, and these are the subject of further discussion, later in this paper. Measures of pairs wider than 5 and which are not orbital have been included elsewhere (Argyle 2011(Argyle , 2013. Corresponding author: rwa@ast.cam.ac.uk The screw value of the Repsold micrometer was determined afresh from measurements of a number of wide pairs whose angular separations are well-known.…”
