TitleThe Guide Star Catalog. II. Photometric and Astrometric Models and Solutions
AuthorsRussell, Jane L.; Lasker, Barry M.; McLean, Brian J.; Sturch, Conrad R.; Jenkner, Helmut
AbstractThe models, algorithms, and procedures used to calibrate the all-sky set of objects in the Guide Star Catalog (GSC) are discussed. The role of the GSC in the Hubble Space Telescope program is reviewed. The photometric reductions and error analysis are described. Consideration is given to the photometric agreement between the GSC and the Guide Star Photometric Catalog, the internal consistency of GSC photometry in pla ...
