VizieR Online Data Catalog: Tucana dSph galaxy spectroscopic dataset (Taibi+, 2020)
Abstract
The primary dataset (P91 FORS2 dataset) analyzed in this work was obtained with the FORS2 instrument mounted at the UT1 (Antu) of the Very Large Telescope (VLT) at the ESO Paranal observatory. Observations were taken in service mode over several nights between July 2013 and July 2014 as part of the ESO program 091.B-0251, PI: M. Zoccali.
The instrumental set-up of the P69 program (Fraternali et al., 2009A&A...499..121F) was similar to the one we adopted for our observations, with the difference being that the size of each slit was of 1.2"x8", which translates into a slightly lower spectral resolution (~30km/s/pix). A total of 45 initial targets were assigned to an equivalent number of slits packed into a single pointing centered on Tucana. For the sake of homogeneity, we therefore reduced the F09 dataset again following the same procedure as adopted for the P91 sample. Hereinafter, we refer to this additional sample as the P69 FORS2 dataset. Gregory et al. (2019MNRAS.485.2010G) recently presented an additional sample of l.o.s. velocities (not metallicities) for individual stars in the direction of Tucana, taken with the FLAMES/GIRAFFE instrument at the VLT, as part of the ESO program 095.B-0133(A), PI: M. Collins. We refer to this sample as FLAMES dataset. (3 data files).- Publication:
