Abstract:
We report broadband UBV and/or BVRCIC CCD photometry for a total
of 1857 stars in the thick-disk and halo populations of the Galaxy.
The majority of our targets were selected as candidate field
horizontal-branch or other A-type stars (FHB/A, N=576), or candidate
low-metallicity stars (N=1221), from the HK and Hamburg/ESO
objective-prism surveys. Similar data for a small number of additional
stars from other samples are also reported.
Description:
The photometry observations reported in the present paper were
conducted over a total of 28 runs with six different
telescope/detector combinations during the period 1998 to 2006. There
were 13 runs with the ESO/Danish 1.5m telescope on La Silla, 10 runs
with the WIYN 0.9m telescope on Kitt Peak, three runs with the CTIO
0.9m (including two conducted by the SMARTS consortium), one run with
the CTIO 1.0m (conducted by the SMARTS consortium), and a single run
with the Hiltner 2.4m telescope at the MDM observatory on Kitt Peak.
