哈勃太空望远镜观测目录是自1990年4月24日发射以来，NASA/ESA哈勃太空望远镜获取的每一次观测的完整索引，数据来源于Mikulski空间望远镜档案馆（MAST）。哈勃的2.4米主镜和一套仪器产生了天文学中最具科学价值的档案之一，已有超过35年的连续低地球轨道运行历史。

目录中的每一行代表一次HST观测——即执行特定仪器、探测器、滤波器和目标指向的曝光时间单位。行数据包括观测的提案（提案ID、PI、标题、类别：GO、SNAP、GTO、DDT、CAL）、目标（名称、坐标、移动/固定标志）、仪器和探测器（ACS WFC/HRC/SBC、WFC3 UVIS/IR、WFPC2 WF/PC、STIS、COS、NICMOS，以及传统的FOC/FOS/HRS/FGS）以及观测意图。

该数据集是回答以下问题的权威参考：哈勃在给定的赤经/赤纬附近观测了什么？哪些提案使用了STIS进行紫外光谱分析？哪些目标的成像覆盖最深？它设计用于与目标目录（星系、类星体、恒星、太阳系天体）进行交叉匹配，用于项目级摘要，规划JWST后续观测，并作为观测推荐系统的训练数据。

此v1版本仅提供观测级别的元数据。每次观测的时间和曝光数据——需要与MAST的`dbo.caomplane`表（460万行）连接——将在v2版本中提供，因为我们正在构建一个异步批处理管道。目前，可以通过MAST门户或`astroquery.mast` Python包按观测检索详细的定时/滤波信息。

该目录源自MAST的CAOM（通用档案观测模型）表`dbo.caomobservation`，并随着HST观测进入档案而每周更新。校准和工程观测也包括在内，但可以通过`intent`列进行区分。

该数据集适用于**表格分类**任务。

The Hubble Space Telescope Observation Catalog is a complete index of every observation acquired by the NASA/ESA Hubble Space Telescope since its launch on April 24, 1990, with data sourced from the Mikulski Archive for Space Telescopes (MAST). Hubble’s 2.4-meter primary mirror and suite of instruments have produced one of the most scientifically valuable archives in astronomy, with over 35 consecutive years of operation in low Earth orbit.

Each row in the catalog represents one HST observation, i.e., a single exposure time unit for conducting observations with specified instruments, detectors, filters, and target pointings. Row data includes observation proposals (proposal ID, PI, title, category: GO, SNAP, GTO, DDT, CAL), targets (name, coordinates, moving/fixed flag), instruments and detectors (ACS WFC/HRC/SBC, WFC3 UVIS/IR, WFPC2 WF/PC, STIS, COS, NICMOS, as well as legacy FOC/FOS/HRS/FGS), and observation intent.

This dataset serves as an authoritative reference for answering questions such as: What observations did Hubble conduct near a given right ascension/declination? Which proposals used STIS for ultraviolet spectroscopic analysis? Which targets have the deepest imaging coverage? It is designed for cross-matching with target catalogs (galaxies, quasars, stars, Solar System bodies), generating project-level summaries, planning JWST follow-up observations, and serving as training data for observation recommendation systems.

This v1 release only provides observation-level metadata. Timing and exposure data for each observation—which requires joining with MAST’s `dbo.caomplane` table (4.6 million rows)—will be provided in the v2 release, as we are currently building an asynchronous batch processing pipeline. Currently, detailed timing/filtering information can be retrieved per observation via the MAST Portal or the `astroquery.mast` Python package.

This catalog is derived from MAST’s CAOM (Common Archive Observation Model) table `dbo.caomobservation`, and is updated weekly as HST observations are archived. Calibration and engineering observations are also included, but can be distinguished via the `intent` column.

This dataset is suitable for **table classification** tasks.
