Part of the EPS Research multi‑epoch kinematic platform: Full datasets, cross‑epoch corpora, executable examples, and the Astro‑Extractor are available at https://github.com/eps-research/rag-corpus-series. # Unified Galaxy HI Rotation Curve Corpus (v7.0) **SPARC + THINGS + LITTLE THINGS + WALLABY DR2** Flynn, D.C. (EPS Research) | ORCID: 0000-0002-2768-6650 | davidflynn@eps-research.com --- Summary Full Platform: This dataset is part of the EPS Research multi‑epoch kinematic platform (SPARC + THINGS + LITTLE THINGS + WALLABY DR2 + z≈6). All corpora, executable notebooks, the Astro‑Extractor, and the unified schema are available at: https://github.com/eps-research/rag-corpus-series Version update (v7.0): Updated corpus files, expanded documentation, and revised ingestion and figure‑generation scripts. Scientific scope unchanged. A unified corpus of **8,963 spatially resolved HI rotation curve measurements across 423 galaxies** from four major surveys, plus kinematic metadata for 15 additional THINGS galaxies (438 total). Designed for both traditional numerical analysis and LLM retrieval-augmented generation (RAG) pipelines. All radii in kpc, all velocities in km/s. Kinematic parameters verified against scanned primary tables. Two-tier quality system: Tier 1 (hand-curated, per-point uncertainties) and Tier 2 (automated WALLABY pipeline). | Survey | Galaxies | Data Points | Tier | Reference ||--------|----------|-------------|------|-----------|| SPARC | 175 | 3,391 | 1 | Lelli et al. (2016), AJ 152, 157 || THINGS | 34 (19 w/data) | 2,110 | 1 | de Blok et al. (2008), AJ 136, 2648 || LITTLE THINGS | 26 | 1,716 | 1 | Oh et al.

# 统一星系中性氢(Hydrogen I,HI)旋转曲线数据集(v7.0) **SPARC + THINGS + LITTLE THINGS + WALLABY DR2** 弗林(D.C. Flynn)(EPS研究机构) | 开放研究者与贡献者身份识别码(ORCID):0000-0002-2768-6650 | 邮箱:davidflynn@eps-research.com --- ## 概述 ### 版本更新说明(v7.0) 本次更新修订了数据集文件,扩充了配套文档,并优化了数据导入与图像生成脚本,科学研究范围未作调整。 本数据集整合了来自4项主流巡天项目的423个星系的8963条空间分辨中性氢(Hydrogen I,HI)旋转曲线测量数据,额外包含15个THINGS星系的运动学元数据,总计覆盖438个星系。本数据集既可用于传统数值分析,也可适配大语言模型(Large Language Model,LLM)检索增强生成(Retrieval-Augmented Generation,RAG)工作流。 所有半径单位均为千秒差距(kiloparsec,kpc),所有速度单位均为千米每秒(kilometers per second,km/s)。运动学参数均通过扫描原始观测表格完成验证。数据集采用两级质量评级体系:一级(Tier 1)为人工审核精选,包含每个数据点的不确定度;二级(Tier 2)为WALLABY自动流水线处理所得。 | 巡天项目 | 星系数量 | 有效数据点数 | 质量等级 | 参考文献 | |--------|----------|-------------|------|-----------| | SPARC | 175 | 3391 | 1 | Lelli等(2016),《天文学期刊》152卷,157页 | | THINGS | 34(其中19个具备有效数据) | 2110 | 1 | de Blok等(2008),《天文学期刊》136卷,2648页 | | LITTLE THINGS | 26 | 1716 | 1 | Oh等(2015),《天文学期刊》149卷,180页 | | WALLABY DR2 | 203 | 1746 | 2 | Deg等(2022);Murugeshan等(2024) | | **总计** | **438** | **8963** | | | ## 数据集文件 - **rotation_curve_corpus_v7.json** — 主JSON文件(约2.0 MB):包含全部438个星系的结构化文档,涵盖按环分组的观测数据、元数据、列定义与质量标注,为数据集的权威源文件。 - **rotation_curve_corpus_v7_flat.csv** — 目录表文件(438行,29列):每个星系对应一行,包含用于筛选与样本选取的汇总统计量。 - **rotation_curve_corpus_v7_by_galaxy.zip** — 按星系分类的JSON归档文件(包含SPARC/THINGS/LITTLE_THINGS/WALLABY四个子目录下的438个独立文件):每个文件均包含完整的数据集元数据与观测信息,针对大语言模型/检索增强生成(LLM/RAG)的数据导入流程进行了优化。 - **corpus_description_sheet_v7.docx** — 完整的数据集官方说明文档。 - **READMEv7.md** — 本说明文件(扩展版本)。 - **wallaby_ingest.py** — WALLABY DR2数据导入脚本(补充材料)。 - **make_figures_v7.py** — 配套天文学与空间科学论文的图像生成脚本(补充材料)。 ## 相关已发表论文 弗林(D.C.
