26 May 1998 | | Subject: | astro-ph | | Affiliation: | 1, 2), Yin-Sheng Sun , Michael C. B. Ashley , Michael G. Burton , Lori E. Allen , and John W. V. Storey ( University of New South Wales, Australia, Joint Astronomy Centre, Hawaii | | Abstract: | We describe the specifications, characteristics, calibration, and analysis of data from the University of New South Wales Infrared Fabry-Perot (UNSWIRF) etalon. UNSWIRF is a near-infrared tunable imaging spectrometer, used primarily in conjunction with IRIS on the AAT, but suitable for use as a visitor instrument at other telescopes. The etalon delivers a resolving power in excess of 4000 (corresponding to a velocity resolution ~75 km/s), and allows imaging of fields up to 100" in diameter on the AAT at any wavelength between 1.5 and 2.4 microns for which suitable blocking filters are available. | | Source: | arXiv, astro-ph/9805325 | | Services: | Forum | Review | PDF | Favorites | |
