APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch,spectroscopic survey of the Milky Way. The second generation of the APOGEEproject, APOGEE-2, includes an expansion of the survey to the SouthernHemisphere called APOGEE-2S. This expansion enabled APOGEE to perform a fullypanoramic mapping of all the main regions of the Milky Way; in particular, byoperating in the H-band, APOGEE is uniquely able to probe the dust-hidden innerregions of the Milky Way that are best accessed from the Southern Hemisphere.In this paper we present the targeting strategy of APOGEE-2S, with specialattention to documenting modifications to the original, previously publishedplan. The motivation for these changes is explained as well as an assessment oftheir effectiveness in achieving their intended scientific objective. Inanticipation of this being the last paper detailing APOGEE targeting, wepresent an accounting of all such information complete through the end of theAPOGEE-2S project; this includes several main survey programs dedicated toexploration of major stellar populations and regions of the Milky Way, as wellas a full list of programs contributing to the APOGEE database throughallocations of observing time by the Chilean National Time Allocation Committee(CNTAC) and the Carnegie Institution for Science (CIS). This work was presentedalong with a companion article, R. Beaton et al. (submitted; AAS29028),presenting the final target selection strategy adopted for APOGEE-2 in theNorthern Hemisphere.
