Abstract:
Spectroscopic and photometric data for likely member stars of five
Galactic globular clusters (M3, M53, M71, M92, and NGC 5053) and three
open clusters (M35, NGC 2158, and NGC 6791) are processed by the
current version of the SEGUE Stellar Parameter Pipeline (SSPP), in
order to determine estimates of metallicities and radial velocities
(RVs) for the clusters. These results are then compared to values from
the literature.
Description:
The spectroscopic data were obtained during SEGUE observations using
the ARC 2.5m telescope, with stars targeted for spectroscopic
follow-up selected from a photometric color-magnitude diagram (CMD)
for each cluster.
