Abstract:
We have obtained metallicities of ∼360 red giant stars distributed in
15 Small Magellanic Cloud (SMC) fields from near-infrared spectra
covering the CaII triplet lines using the VLT + FORS2.
Description:
Recently, we determined metallicities and RVs for a sample of SMC
clusters based on CaT spectroscopy of red giant stars (Paper I). As
part of Program 076.B-0553, V- and I-band pre-images of our targets
were taken by ESO Paranal staff in 2005 August.
The spectra of the program stars were obtained during 2005 November in
service mode by the Very Large Telescope (VLT) staff, using the FORS2
spectrograph in mask exchange unit (MXU) mode.
