Abstract

We propose to finalize the compilation of a comprehensive database of high-quality
ages and metallicities of Simple Stellar Populations (SSPs) in the Milky Way and the
Magellanic Clouds. We will acquire new ACS imagery for 8 young and intermediate-age
globular clusters in the Magellanic Clouds to create high-quality color-magnitude
diagrams (CMDs) to enable accurate measurements of their ages and metallicities. In
concert with a similar analysis of CMD data already available in the HST archive for
8 more such GCs, the resulting database will provide a well-sampled coverage of the
full range of ages and metallicities known among globular clusters (0.5 <= Age (Gyr)
<= 13.5 and -2.3 <= [Fe/H] <= +0.1, respectively). This database will form the
crucial basis for our ongoing, comprehensive multi-wavelength program to: (1)
establish empirical relations among SSP colors (from the UV [GALEX] through the mid-
IR [Spitzer]), line strengths, ages and metallicities, and (2) provide a stringent
test of the systemic accuracy of age and metallicity determinations using state-of-
the-art population synthesis models.

  Observations Description
  ------------------------

     The target globular clusters younger than an estimated age of about 4 Gyr are
     observed in F435W, F555W and F814W except for the older cluster ESO 121-SC03,
     which is observed in F435W, F606W, and F814W (since good CMDs for "old"
     Galactic clusters straddling the estimated metallicity of ESO 121-SC03 are only
     available in ACS/WFC F606W, not in F555W), using ACS/WFC. Three filters are
     used to improve the age estimate (relative to the use of only two filters) and
     to enable an estimate of the reddening for these clusters. Since the shape and
     position of the giant branch is used to determine metallicities, it is
     imperative to involve exposures in each filter that do not saturate the bright
     giants. On the other hand, an accurate age determination by comparing the CMD
     with isochrones requires color uncertainties of about 0.1 mag at or slightly
     beyond the estimated turnoff magnitude, which dictates the need for long
     exposures as well. Hence, a short exposure is used in each filter to avoid
     saturation of the brightest giants (and the turn-off stars for the youngest
     clusters), while two or three longer exposures are used to reach a depth
     sufficiently beyond the estimated turnoff magnitude. Two dither positions per
     cluster are used. The orbit lengths are set to 70 min. This doesn't impede
     their schedulability at the declination of the Large Magellanic Cloud according
     to the visit planner.

  Real Time Justification
  -----------------------

     As requested in Phase I, we will observe ESO 121-SC03 in the Continuous Viewing
     Zone. The fact that the Earthshine will be somewhat higher during CVZ orbits
     than during non-CVZ orbits is not detrimental for the proposed observations,
     since the limiting factor for S/N ratios in our case is the `background'
     associated with the crowded star field of the LMC.
