VizieR Online Data Catalog: Abundances of red giants in M4 and 47 Tuc (Carretta+, 2013)
Abstract
The present work is based on two exposures, the first of 2700s at airmass 1.487 (seeing=1.23") acquired on 2010, July 30 for 47 Tuc and the second of 1600s at airmass 1.240 (seeing=1.79") taken on 2010, April 14 with FLAMES@VLT-UT2 and the high-resolution grating HR21. The resolution is 17300 at the center of the spectra, and the spectral range goes from about 8484 to about 9001Å, including the AlI doublet at 8772-73Å, which is the main feature we were interested in.
