欧几里得空间望远镜Q1数据发布-catalogs数据

Euclid Q1的星表数据包含6个目录，6个星表目录分别是--MER_FINAL_CATALOG:合并“马赛克”图像获得的主星表，包括测光和形态信息;NIR_CAL_CATALOG:基于校准过的近红外分光光度计和光度计图像测量而得到的星表;PHZ_PF_OUTPUT_CATALOG 和 PHZ_PF_OUTPUT_FOR_L3:测光红移星表; SPE_PF_OUTPUT_CATALOG:光谱学星表;VIS_CAL_CATALOG:基于校准过的可见光仪器拍摄的图像测量获得的星表。目录下的星表文件都是fits文件，更多数据内容详情参考https://irsa.ipac.caltech.edu/data/Euclid/docs/euclid_archive_at_irsa_user_guide.pdf。The catalog data of Euclid Q1 consists of 6 catalogs. Specifically, the six catalogs are as follows: MER_FINAL_CATALOG: the master catalog generated by merging "mosaic" images, which includes photometric and morphological information; NIR_CAL_CATALOG: the catalog derived from measurements on calibrated near-infrared spectrophotometer and photometer images; PHZ_PF_OUTPUT_CATALOG and PHZ_PF_OUTPUT_FOR_L3: photometric redshift catalogs; SPE_PF_OUTPUT_CATALOG: spectroscopic catalog; VIS_CAL_CATALOG: the catalog obtained from measurements on images captured by calibrated visible-light instruments. All catalog files under these catalogs are in FITS format.
