Data and Software for: Resolved Near-infrared Stellar Photometry from the Magellan Telescope for 13 Nearby Galaxies: JAGB Method Distances

12/17/24 Update: I was made aware that the MRT files had the J-band and H-band column header labels incorrectly switched (this occured when converting the CSV files to MRT). I have fixed this mistake in this version. The CSV files were correct the entire time. No data have been changed. Apologies for any inconvinence this may have caused. Data for Resolved Near-infrared Stellar Photometry from the Magellan Telescope for 13 Nearby Galaxies: JAGB Method Distances The files are provided in two formats. A CSV format with a single line header, and a MRT files (zipped) written in the machine-readable format used by AAS & CDS: https://journals.aas.org/mrt-overview/ Column descriptions in photometry catalogs: X/Y: Image coordinates from Fourstar camera J, J_err: J-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME H, H_er: H-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME K, K_err: K-band magnitudes and photometric errors returned from DAOPHOT/ALLFRAME chi: chi value returned from DAOPHOT/ALLFRAME sharp: sharpness value returned from DAOPHOT/ALLFRAME ra/dec: RA/Decl RGC: semi-major axis distance Notes on versions: all catalogs from all versions contain the same information, style was just adjusted to adhere to AAS standards.2024年12月17日更新：我方获悉，此前MRT格式文件的J波段（J-band）与H波段（H-band）列标题标签存在错误互换（该问题产生于CSV文件转MRT格式的过程中）。本版本已修复此问题，CSV文件自始至终均为正确版本，未改动任何数据。为该问题带来的不便致歉。 13个邻近星系的麦哲伦望远镜（Magellan Telescope）解析近红外恒星测光数据：JAGB法（JAGB Method）距离测算结果 本数据集提供两种格式文件：一是带单行表头的CSV格式文件，二是经压缩的MRT格式文件，该格式采用美国天文学会（American Astronomical Society, AAS）与斯特拉斯堡天文数据中心（Centre de Données astronomiques de Strasbourg, CDS）所使用的机器可读格式，详情参见：https://journals.aas.org/mrt-overview/ 测光星表的列字段说明： X/Y：Fourstar相机（Fourstar camera）获取的图像坐标 J、J_err：DAOPHOT/ALLFRAME程序输出的J波段星等及测光误差 H、H_err：DAOPHOT/ALLFRAME程序输出的H波段星等及测光误差 K、K_err：DAOPHOT/ALLFRAME程序输出的K波段星等及测光误差 chi：DAOPHOT/ALLFRAME程序输出的chi拟合值 sharp：DAOPHOT/ALLFRAME程序输出的sharp锐度值 ra/dec：赤经/赤纬（RA/Decl） RGC：半长轴距离 版本说明：所有版本的星表均包含完全一致的信息，仅对格式样式进行了调整以符合美国天文学会（AAS）的规范要求。
