Abstract:
The Chandra Source Catalog (CSC) is a general purpose virtual X-ray
astrophysics facility that provides access to a carefully selected set
of generally useful quantities for individual X-ray sources, and is
designed to satisfy the needs of a broad-based group of scientists,
including those who may be less familiar with astronomical data
analysis in the X-ray regime. The first release of the CSC includes
information about 94,676 distinct X-ray sources detected in a subset
of public Advanced CCD Imaging Spectrometer imaging observations from
roughly the first eight years of the Chandra mission. This release of
the catalog includes point and compact sources with observed spatial
extents < 30''. The catalog (1) provides access to the best estimates
of the X-ray source properties for detected sources, with good
scientific fidelity, and directly supports scientific analysis using
the individual source data; (2) facilitates analysis of a wide range
of statistical properties for classes of X-ray sources; and (3)
provides efficient access to calibrated observational data and
ancillary data products for individual X-ray sources, so that users
can perform detailed further analysis using existing tools. The
catalog includes real X-ray sources detected with flux estimates that
are at least 3 times their estimated 1-sigma uncertainties in at
least one energy band, while maintaining the number of spurious
sources at a level of < 1 false source per field for a 100ks
observation. For each detected source, the CSC provides commonly
tabulated quantities, including source position, extent, multi-band
fluxes, hardness ratios, and variability statistics, derived from the
observations in which the source is detected. In addition to these
traditional catalog elements, for each X-ray source the CSC includes
an extensive set of file-based data products that can be manipulated
interactively, including source images, event lists, light curves, and
spectra from each observation in which a source is detected.
Description:
This version of the catalog is release 1.1. It includes the
information contained in release 1.0.1, plus point and compact source
data extracted from HRC imaging observations, and catch-up ACIS
observations released publicly prior to the end of 2009.
