Abstract

We present a methodology for the regularization and combination of sparse sampled and irregularly gridded observations from fibre-optic multiobject integral field spectroscopy. The approach minimizes interpolation and retains image resolution on combining subpixel dithered data. We discuss the methodology in the context of the Sydney-AAO multiobject 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 1° diameter field of view. The SAMI Galaxy Survey is targeting ~3000 galaxies drawn from the full range of galaxy environments. We demonstrate the sub..

The SAMI Galaxy Survey is based on observation made at the Anglo-Australian Telescope (AAT). The Sydney-AAO Multiobject Integral field spectrograph (SAMI) was developed jointly by the University of Sydney and the Australian Astronomical Observatory. The SAMI input catalogue is based on data taken from the Sloan Digital Sky Survey, the GAMA Survey and the VST ATLAS Survey. The SAMI Galaxy Survey is funded by the Australian Research Council Centre of Excellence for All-sky Astrophysics (CAASTRO, CE1100010200) and other participating institutions. The SAMI Galaxy Survey website is http://sami-survey.org. We thank the dedicated staff at the AAT whose support in interfacing SAMI with AAOmega is invaluable.MSO and JTA acknowledge the funding support from the Australian Research Council through a Super Science Fellowship (ARC FS110200023 and FS110200013).
