12 Oct 2001 | Journal: | Mon.Not.Roy.Astron.Soc. 329 (2002) 759 | Subject: | astro-ph | Affiliation: | ESO Chile), P. L. Shopbell (Caltech) and J. Bland-Hawthorn (AAO | Abstract: | The past five years have seen a rapid rise in the use of tunable filters in many diverse fields of astronomy, through Taurus Tunable Filter (TTF) instruments at the Anglo-Australian and William Herschel Telescopes. Over this time we have continually refined aspects of operation and developed a collection of special techniques to handle the data produced by these novel imaging instruments. In this paper, we review calibration procedures and summarize the theoretical basis for Fabry-Perot photometry that is central to effective tunable imaging. Specific mention is made of object detection and classification from deep narrowband surveys containing several hundred objects per field. We also discuss methods for recognizing and dealing with artefacts (scattered light, atmospheric effects, etc.) which can seriously compromise the photometric integrity of the data if left untreated. Attention is paid to the different families of ghost reflections encountered, and strategies to minimise their presence. In our closing remarks, future directions for tunable imaging are outlined and contrasted with the Fabry-Perot technology employed in the current generation of tunable imagers. | Source: | arXiv, astro-ph/0110289 | Services: | Forum | Review | PDF | Favorites |
