This paper reports quantification and explanation of some sources of error in using the Reduc software to measure the PA and separation of double star images.
Double Stars
In 2014, Tim Napier-Munn was awarded the Page Medal for work on binary stars systems and for demonstrating a deep understanding of observational techniques and processes that will progress the field.
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.
Measurements have been made of eight neglected southern multiple stars from the Washington Double Star Catalogue. Images were acquired using a Meade DSI CCD camera coupled to a 150mm f/8 refractor, and analysed using Losse’s Reduc software.
Measurements of six neglected southern multiple stars have been made using a Meade DSI CCD camera coupled to a 150mm f8 refractor.
