AI总结：
本文介绍了PLATO任务首个长持续观测阶段（LOPS2）的目标输入目录（tPIC2.2），利用Gaia DR3数据和星际介质三维地图，确定了217741颗恒星，包括202315颗FGK矮星、15037颗M矮星和789颗已知行星宿主恒星，并估计了星际红化和恒星参数。
摘要：
ESA PLAnetary Transits and Oscillations of stars（PLATO）任务旨在探测太阳型恒星的适居带类地行星。由于 telemetry 限制，PLATO目标的选择必须提前进行。本文介绍了PLATO目标输入目录（tPIC2.2）的首次公开发布，该目录提供了PLATO首个长持续观测阶段（LOPS2）南半球观测的恒星列表，作为其核心科学计划的一部分。我们利用Gaia数据释放3（DR3）的视差和光度数据，以及本地星际介质的三维地图，确定符合任务要求的恒星样本。tPIC包含217741颗恒星，包括202315颗FGK矮星和亚巨星、15037颗M矮星和789颗已知行星宿主恒星。FGK恒星的中位距离为512 pc，M矮星为133 pc。我们估计了几乎所有目标的星际红化，并开发了一种算法，从视差和光度观测中一致地推断基本恒星参数（有效温度、半径和质量）。tPIC满足了PLATO任务的所有科学要求。此外，tPIC还包含位于LOPS2场内的已知行星宿主恒星列表（确认或仍为候选）。
英文摘要：
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission is designed to detect terrestrial planets in the habitable zones of solar-type stars. Owing to telemetry constraints, the selection of PLATO targets must be performed in advance. We present the first public release of the PLATO Input Catalog of targets (tPIC2.2), which provides the list of stars that will be observed during PLATO's first Long-duration Observation Phase field at South (LOPS2) as part of its core science program. We used astrometric and photometric data from Gaia data release 3 (DR3), together with three-dimensional maps of the local interstellar medium, to identify stars belonging to the PLATO stellar samples in accordance with the mission requirements. The tPIC comprises 217,741 stars, including 202,315 FGK dwarfs and subgiants, 15,037 M dwarfs, and 789 known planet-host stars. The median distances of the samples are 512 pc for FGK stars and 133 pc for M dwarfs. We estimated interstellar reddening for almost all targets and developed an algorithm to infer fundamental stellar parameters (effective temperature, radius, and mass) homogeneously from astrometric and photometric observables. The tPIC fulfills all the science requirements of the PLATO mission. It also includes a list of stars that host known exoplanets, confirmed or still candidate, located within the LOPS2 field.
