Abstract:
We have tabulated lists of upper red giant, horizontal-, and
asymptotic giant branch (RGB, HB, and AGB) stars in the globular
cluster M5 that are complete to over 10' from the core for the RGB and
AGB samples, and 8' for the HB sample. The large samples give us the
most precise value of R2=NAGB/NHB to date for a single globular
cluster (0.176±0.018).
Description:
In order to collect a nearly complete sample of bright evolved stars
in M5, we used data from a variety of sources. The primary source of
ground-based photometry was the study of Sandquist et al.
(1996ApJ...470..910S 1996ApJ...470..910S). That data set was composed of BVI photometry
taken at the Cerro Tololo Inter-American Observatory (CTIO) 4m
telescope and BI images of the cluster core taken using the High
Resolution Camera (HRCam) on the 3.5m Canada-France-Hawaii Telescope
(CFHT). The CFHT data were obtained during very good seeing conditions
so that there was little ambiguity as to the population
identifications of cluster stars. We have also used Hubble Space
Telescope (HST) data from the cluster core reported in Piotto et al.
(2002, Cat. J/A+A/391/945). The F439W and F555W bands were
calibrated to B and V by that group.
