Galactic to Equatorial coordinates for ISM Spectra

This table contains a mapping from Gaia's Galactic to equatorial coordinates. The mapping is meant to be used with the GaiaFPR ISM Spectra table and enables IVOA ConeSearch capabilities. The transformation from galactic to equatorial coordinates follows Chapter 4.1.7 from the official documentation of GaiaDR3.

本表格提供盖亚（Gaia）银河坐标系至赤道坐标系的坐标映射关系。该映射可与盖亚FPR星际介质光谱（GaiaFPR ISM Spectra）表格配合使用，并支持国际虚拟天文台联盟（IVOA）锥搜索（ConeSearch）功能。本次坐标转换严格遵循盖亚第三批数据发布（Gaia DR3）官方文档第4.1.7章的相关规定。
