VizieR Online Data Catalog: Elemental abundances of 416 stars in 5 dSphs of M31 (Kirby+, 2020)
Abstract
Using the DEep Imaging Multi-Object Spectrograph (DEIMOS) at the Keck observatory, Hawaii, in the fall seasons of 2015, 2016, and 2017, we obtained spectroscopy (spectral range ~6300-9100Å) of individual red giants in five M31 dwarf spheroidal satellites (dSphs): Andromeda VII, I, III, V, and X.
The deep spectroscopic slitmasks were designed using results from slitmasks previously observed for approximately one hour as part of the Spectroscopic Landscape of Andromeda's Stellar Halo survey (SPLASH; e.g., Guhathakurta+ 2006AJ....131.2497G and Gilbert+ 2009ApJ...705.1275G and 2012ApJ...760...76G). The photometry used to design slitmasks presented in this paper is exclusively from the Mosaic imager at Kitt Peak National Observatory. The photometry was obtained by Beaton (2014PhDT.......416B) in the Washington system (M and T2 filters), which we transformed to the Cousins system (V and I filters) following Majewski+ (2000AJ....120.2550M). Images were also obtained with the DDO51 filter. Table1 gives the data for each slitmask. (2 data files).- Publication:
