Abstract

We present a methodology for the regularisation and combination of sparse sampled and irregularly gridded observations from fibre-optic multi-object integral-field spectroscopy. The approach minimises interpolation and retains image resolution on combining sub-pixel dithered data. We discuss the methodology in the context of the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) Galaxy Survey underway at the Anglo-Australian Telescope. The SAMI instrument uses 13 fibre bundles to perform high-multiplex integral-field spectroscopy across a one degree diameter field of view. The SAMI Galaxy Survey is targeting 3000 galaxies drawn from the full range of galaxy environments. We demonstrate the subcritical sampling of the seeing and incomplete fill factor for the integral-field bundles results in only a 10% degradation in the final image resolution recovered. We also implement a new methodology for tracking covariance between elements of the resulting datacubes which retains 90% of the covariance information while incurring only a modest increase in the survey data volume., Comment: 17 pages, 10 figures, Accepted MNRAS September 2014

4. Optimal Extraction of Fibre Optic Spectroscopy

Abstract

We report an optimal extraction methodology, for the reduction of multi-object fibre spectroscopy data, operating in the regime of tightly packed (and hence significantly overlapping) fibre profiles. The routine minimises crosstalk between adjacent fibres and statistically weights the extraction to reduce noise. As an example of the process we use simulations of the numerous modes of operation of the AAOmega fibre spectrograph and observational data from the SPIRAL Integral Field Unit at the Anglo-Australian Telescope., Comment: Accepted for publication in PASA

Abstract

Objective: This study aimed to characterise the laryngological presentations of Ehlers–Danlos syndrome and conduct a preliminary exploration of patient-reported outcome measures. Methods: This paper describes a retrospective case series of patients with Ehlers–Danlos syndrome seen by the senior author between 2005 and 2019. A literature review was conducted to summarise the existing findings. Results: Twenty-one patients met the inclusion criteria. All reported symptoms were grouped; this showed that swallowing, voice and hyolaryngeal skeletal complex problems were commonest. Patient-reported outcome measures were available for eight patients, which showed large variations in: the Reflux Severity Index (median = 25.5; range = 0–33), Eating Assessment Tool score (median = 21.5; range = 0–35) and Voice Handicap Index (median = 21.5; range = 0–104). Twelve studies met our literature review inclusion criteria, involving at least 91 patients with laryngological presentations of Ehlers–Danlos syndrome. Conclusion: Ehlers–Danlos syndrome patients experience musculoskeletal issues, which in the throat manifest as hyolaryngeal skeletal complex problems. Future studies with larger patient numbers are required to validate laryngological patient-reported outcome measure tools in Ehlers–Danlos syndrome. [ABSTRACT FROM AUTHOR]
