Data for: The Chicago-Carnegie Hubble Program: The JWST J-region Asymptotic Giant Branch (JAGB) Extragalactic Distance Scale
收藏资源简介:
Photometry for the JAGB stars analyzed in The Chicago-Carnegie Hubble Program: The JWST J-region Asymptotic Giant Branch (JAGB) Extragalactic Distance Scale. These data were used to produce Figure 4. That data are provided in a CSV format with a single line header. Column descriptions: ra/dec: RA/Decl RGC: semi-major axis distance F115W: F115W magnitudes as measured by DOLPHOT F356W: F356W magnitudes as measured by DOLPHOT F444W: F444W magnitudes as measured by DOLPHOT The python script "jagb_der.py" was used to numerically calculate the derivative of m_{JAGB} with respect to radial distance.
本数据集对应《芝加哥-卡内基哈勃计划:JWST J波段渐近巨星支(J-region Asymptotic Giant Branch, JAGB)河外距离尺度》一文中所分析的JAGB恒星测光数据,该数据用于制作图4。 该数据集以逗号分隔值(Comma-Separated Values, CSV)格式存储,附带单行表头。 列说明: ra/dec:赤经(Right Ascension, RA)/赤纬(Declination, Dec) RGC:半长轴距离 F115W:由DOLPHOT软件测得的F115W星等 F356W:由DOLPHOT软件测得的F356W星等 F444W:由DOLPHOT软件测得的F444W星等 本次研究使用Python脚本"jagb_der.py"对m_JAGB随径向距离的导数进行了数值计算。
