Creating updated, scientifically-calibrated mosaics for the RC3 Catalogue

by Doris Lee for Laboratory for Cosmological Data Mining

Using the latest SDSS DR10 data, we provide color composite images and scientifically-calibrated FITS mosaics in all SDSS imaging bands, for all the RC3 galaxies that lie within the survey’s footprint. Due to the positional inaccuracy inherent in the RC3 catalog, the mosaicking program uses a recursive algorithm for positional update first, then conduct the mosaicking procedure.The program is generalized into a pipeline,which can be easily extended to future survey data or other source catalogs.
