VizieR Online Data Catalog: Magellan/M2FS spectroscopy of Tucana 2 and Grus 1 (Walker+, 2016)
Abstract
We observed Tuc 2 and Gru 1 with the Michigan/Magellan Fiber System (M2FS) at the 6.5m Magellan/Clay telescope at Las Campanas Observatory, Chile, on the nights of July 17 (Tuc 2) and July 18 (Gru 1) 2015. We obtained repeat observations of the Tuc 2 field on 2015 September 12.
We selected spectroscopic targets from the photometric catalogs that K15 (Koposov+ 2015ApJ...805..130K) generated from public images taken as part of the Dark Energy Survey (DES; Bechtol+, 2015ApJ...807...50B). DES is a wide-field optical imaging survey in the grizY bands performed with the Dark Energy Camera (DECam) installed at the prime focus of the 4m Blanco telescope at Cerro Tololo Inter-American Observatory. The full DES survey is scheduled for 525 nights distributed over 5 years. Uncertainties in the offsets between the DES photometric system and the AB system are estimated to be ~1%.
