Graeme Jenkinson has published a paper on 17 southern multiple systems in the Webb Society Double Star Section Circulars.

Abstract

This paper presents the results of a 2013/early 2014 programme of photographic measurements of seventeen southern multiple stars. The images were obtained using a Meade DSI CCD camera in conjunction with an equatorially mounted 150-mm f/8 refractor and software programme AstroPlanner 2.1 (Rodman). Image processing was carried out using Losse’s Reduc software. The mean 95% confidence intervals for the new measures were ± 0◦.250 in PA and ± 0′′.112 in separation.
