Compositions and kinematics of the Cloud populations:
Spectra of many stars down to the subgiant branch across the LMC and SMC provide the abundance information to build the age-metallicity relationship in the Clouds over a wider range of ages than the small number of clusters allow. In particular, one can investigate the spatial variation of abundance enhancement history.
The same spectra can be used to ascertain the presence and properties of any intervening stellar population between the LMC and the Galaxy, to identify any spectroscopic binaries that may be helpful in deriving an independent distance, and to identify the kinematic signatures of LMC/SMC/Milky Way interactions.
About 15 pointings are required across the LMC (roughly 5 deg in diameter), plus another ~6 to investigate the SMC. Each pointing will utilize the maximum number of slitlets (~5000) at moderate resolution (R ~ 5000).
