摘要
APOGEE是一项高分辨率(R~22,000)、近红外、多历元、银河系光谱巡天。APOGEE项目的第二代APOGEE-2包含向南半球扩展的APOGEE-2S。该扩展使APOGEE能够对整个银河系所有主要区域进行全景式制图；特别地，通过在H波段工作，APOGEE能够独特地探测从南半球最佳访问的、被尘埃遮蔽的银河系内部区域。本文中我们呈现APOGEE-2S的选源策略，特别关注记录对原先已发表计划的修改。解释了这些变更的动机，并评估了其在实现预期科学目标上的有效性。鉴于这是最后一篇详述APOGEE选源的论文，我们给出了直至APOGEE-2S项目结束的所有此类信息汇总；这包括若干致力于探索银河系主要恒星族与区域的主巡天计划，以及通过智利国家时间分配委员会(CNTAC)和卡内基科学研究所(CIS)分配观测时间贡献于APOGEE数据库的全部计划列表。本工作与companion文章R. Beaton等人(已投稿; AAS29028)一同展示，后者呈现了北半球APOGEE-2采用的最终目标选择策略。
