Abstract:
We present low-resolution (R∼850) spectra for 67 asymptotic giant
branch (AGB), horizontal branch, and red giant branch (RGB) stars in
the low-metallicity globular cluster NGC 5466, taken with the VIRUS-P
integral-field spectrograph at the 2.7m Harlan J. Smith telescope at
McDonald Observatory.
Description:
We determined photometry for members of NGC 5466 based on CCD frames
obtained by H.E.B. with the Kitt Peak National Observatory 0.9m
telescope on 1997 May 9.
On 2009 March 3-5 and July 28-29, we observed four fields in NGC 5466
for a total of 22 hr with the Visible Integral-field Replicable Unit
Spectrograph prototype (VIRUS-P) on the 2.7m Harlan J. Smith Telescope
at McDonald Observatory.
Spectra were acquired for six RGB stars in NGC 5466 by GHS in 2003,
using the LRIS double spectrograph at the W.M. Keck Observatory on
Mauna Kea.
