摘要
APOGEE-2是一项双半球、近红外(NIR)光谱巡天，旨在绘制银河系的化学动力学地图。APOGEE-2的选源复杂且随时间演进。本文中，我们呈现对Zasowski等人(2017)提出的APOGEE-2N初始选源策略的更新与补充。这些修改以两种实施模式出现：(i) “辅助科学计划”通过2015与2017年的提案征集竞争性授予SDSS-IV的首席研究者，以在主巡天之外追求新科学方向；(ii) 凭借APOGEE-2N项目前几年累积的效率提升而成为可能的约1.5年巡天扩展，即亮时间扩展。针对23个不同的辅助计划，我们提供科学目标、目标选择的描述，以及如何在APOGEE-2样本中识别这些目标。亮时间扩展允许更改主巡天策略、纳入响应科学发现或利用巡天设计初期不可得的主要新数据集的新计划，以及扩展现有计划以提升其科学成效与覆盖面。在描述这些计划的动机、实施与评估后，我们还留下了近十年APOGEE-1与APOGEE-2巡天操作的经验总结。 companion论文Santana等人(已投稿)补充呈现了与南半球APOGEE-2操作相关的选源修改。
