Improving GSC-II for JWST Brian McLean et al. (Archive Services Branch) & WIT • Photometric Calibrations • Better estimate of magnitude errors • Recalibrate using latest version of GSPC-II • Use SDSS as additional calibration • Astrometric Calibrations • Recalibrate using UCAC3 as reference catalog improve proper motion • Catalog Augmentation • Augment GSC-II with 2MASS sources that are not cross matched with GSC-II • Develop generalized schema to incorporate additional catalogs as needed February 19, 2009
