Graeme Jenkinson and Tim Napier-Munn have published a paper on neglected souther multiple systems in Pavo in the Webb Society Double Star Section Circulars.
Measurements have been made of 24 southern multiple stars from the Washington Double Star Catalogue. Images were acquired using a Meade DSI CCD camera coupled to a 150mm f8 refractor, and analysed using Losses Reduc software. The imaging and reduction methods were described in detail in DSSC 17. The mean 95% confidence intervals for the new measures were ± 0◦.79 in PA and ± 0′′.26 in separation.
