摘要
为满足 PLATO 太空任务的科学目标，已设计了广泛的科学校准与验证计划。本文描述了该计划以及用于选择已进入其输入目录中科学校准与验证星的 methodology。这是所谓的 {\tt scvPIC}，它是首个选定的南半球长期观测场 (LOPS2) 的通用 PLATO 输入目录 (PIC) 的一部分。尽管 PLATO 的许多科学要求都需要专用校准星，但其最严格的要求是：对于亮度为 {\it V} = 10 星等的 G0V 型恒星，交付其系星年龄的精度better than 10\%。这目前尚未在银河系中大规模的致密星和亚光星群体中实现，因为这需要改进其内部星体模型。我们讨论了这一野心式的年龄要求如何导致选取数万颗红巨星以及数千颗主序早 F 型重力模态振荡器，以推断其在星演化过程中的内部旋转轮廓。这种 asteroseismic 可观测量将被导入到改进的 Milky Way 中致密星和亚光星的模型中，以作为永远更精确年龄dating 星系 host 的优化建模工具，随着 PLATO 任务的推进。{\tt scvPIC} 中此外的校准器和验证器包括数千颗双星、数百颗遗留基准星、数百颗光度稳定星以及六颗流变棕色星体。
