Abstract:
We summarize a selection process to identify red giants in the
direction of the southern warp of the Galactic disk, employing
VIC photometry and multi-object spectroscopy.
Description:
We observed warp field 1a with the University of Michigan's Curtis
Schmidt telescope at the Cerro Tololo Inter-American Observatory using
a 1024x1024 Thompson CCD with an image scale of 1.835"/pix and a field
of view of 31'x31'. The 24-fiber multiobject Argus echelle spectrograph
was used at the prime focus of the Cerro Tololo Inter-American
Observatory 4.0m Blanco Telescope in March of 1994. Single-order
spectra centered on the Mg b triplet (∼5200Å) were obtained for
209 of the stars that appear to be field red giants.
