Multiple RHB Populations in Globular Clusters - AstroSat NUV Photometry of Modelled Stars
收藏资源简介:
This deposition consists of two datasets: RHBI.txt RHBII.txt These datasets contain the AstroSat UVIT photometry of 18 red horizontal branch (RHB) stars from the globular cluster NGC 2808, which were selected for modelling in the study titled ''Multiple RHB Populations in Globular Clusters''. Each dataset contains the photometry of 9 stars (in 6 near-UV filters) belonging to one of the two RHB groups (RHBI and RHBII) present in NGC 2808. Each dataset contains the following columns: ID - The number/name of the source. XC, YC - Image coordinates RA, Dec - Right Ascension and Declination of the source in J2000 epoch. NF6, NF5, NF3, NF2, NF1 - Photometric magnitude (in ABmag) of source in the filters N279N, N263M, N245M, N219M and N242W respectively. ERRF6, ERRNF5, ERRNF3, ERRNF2, ERRNF1 - Error in photometric magnitude (in ABmag) of source in the filters N279N, N263M, N245M, N219M and N242W respectively.
