Beginning of ReadMe : I/324 The Initial Gaia Source List (IGSL) (Smart, 2013) ================================================================================ The Initial Gaia Source List (IGSL) Smart R.L., Nicastro L. <ESA Document Gaia-C3-TN-OATO-RLS-004-01 > =2013yCat.1324....0S =2014A&A...570A..87S ================================================================================ ADC_Keywords: Positional data ; Proper motions ; Photometry, photographic Cross identifications Keywords: catalogs - surveys - astrometry Mission_Name: Gaia Abstract: The Initial Gaia Source List will be the starting point for the Gaia Initial Data Treatment. The Attitude Star Catalog will be used by the first iteration of the on-ground attitude reconstruction. Description: The IGSL is a compilation catalog produced for the Gaia mission. We have combined data from the following catalogs or datasets to produce a homogenous list of positons, proper motions, photometry in a blue and red band and estimates of the magnitudes in the Gaia G and G_RVS bands. Included Catalogs: Tycho2, LQRF, UCAC4, SDSS-DR9, PPMXL, GSC23, GEPC, OGLE, Sky2000, 2MASS. Note that in compiling the various entries we did not consider the individual flags. Overall, we think this catalog is reliable but there will be errors, mismatches and duplicates. The user should use this catalog with that in mind, it is fine for statistical studies that has some way to remove obviously incorrect entries but it should only be used with care for individual objects. The source catalogs used to produce the IGSL are: * The Gaia Ecliptic Pole Catalog, version 3.0 (GEPC) Altmann & Bastian 2009, "Ecliptic Poles Catalogue Version 1.1" ESA Document GAIA-C3-TN-ARI-MA-002 URL http://www.rssd.esa.int/llink/livelink/open/2885828 * GSC2.3: GSC2 version 2.3, Lasker et al. 2008AJ....136..735L (I/305) * an excerpt of the 4th version of the Gaia Initial QSO Catalog (GIQC) as compiled by the GWP-S-335-13000, formed by Alexandre H. Andrei, Christophe Barache, Dario N. da Silva Neto, Francois Taris, Geraldine Bourda, Jean-Francois Le Campion, Jean Souchay, J.J. Pereira Osorio, Julio I. Bueno de Camargo, Marcelo Assafin, Roberto Vieira Martins, Sebastien Bouquillon, Sebastien Lambert, Sonia Anton, Patrick Charlot * OGLE: Optical Gravitational Lensing Experiment version III (Szymaski et al., 2011, Cat.
