The ASCA Medium Sensitivity Survey (the GIS Catalog Project):: Source catalog II

In succession to the first ASCA Medium Sensitivity Survey catalog (AMSS-I), we present the second X-ray source catalog (AMSS-II), constructed from the Gas Imaging Spectrometer data covering Galactic latitudes vertical bar b vertical bar > 10 degrees observed between 1997 January and 2000 May. The AMSS-II catalog uses 306 fields and contains a total of 1190 sources detected with significance of > 5 sigma in either the 0.7-7, 2-10, or 0.7-2 keV band. The AMSS-I and AMSS-II catalogs list a total of 2533 sources from an area of 278 deg(2) and provides a unique database of X-ray sources in the flux range of 10(-13)-10(-11) ergs cm(-2) s(-1) (0.7-10 keV). We summarize statistical properties of a complete X-ray sample consisting of 1969 serendipitous selected from AMSS-I and AMSS-II.
