论文摘要
语境。作为Gaia数据版本3（GAIA DR3）的一部分，Epoch光度法已以120万个以M31为中心的来源发布。这是Gaia Data Release 4的品尝者，其中所有时期的光度法都将被释放。目标。在本文中，描述了Gaia仙女座光度测量的内容，包括评估数据质量的统计数据。还概述了光度法的已知问题。方法。给出了改善光度法解释的方法，尤其是一种误差重新归一化的方法。同样，使用三个光度传递带之间的相关性可以更清楚地识别不受系统效应引起的错误检测影响的变量。结果。 Gaia Andromeda光度法调查提供了一个独特的机会，可以查看由于可变性而未经预选的Gaia Epoch光度法。这允许进行调查，可以使用平均源结果将其应用于天空的其余部分。另外，可以在M31和银河系上进行可变性的科学研究。
Context. As part of Gaia Data Release 3 (Gaia DR3), epoch photometry has been released for 1.2 million sources centred on M31. This is a taster for Gaia Data Release 4 where all the epoch photometry will be released. Aims. In this paper the content of the Gaia Andromeda Photometric Survey is described, including statistics to assess the quality of the data. Known issues with the photometry are also outlined. Methods. Methods are given to improve interpretation of the photometry, in particular, a method for error renormalization. Also, use of correlations between the three photometric passbands allows clearer identification of variables that is not affected by false detections caused by systematic effects. Results. The Gaia Andromeda Photometric Survey presents a unique opportunity to look at Gaia epoch photometry that has not been preselected due to variability. This allows investigations to be carried out that can be applied to the rest of the sky using the mean source results. Additionally scientific studies of variability can be carried out on M31 and the Milky Way in general.
