Abstract:
We present a catalog of high Galactic-latitude (|b|>10deg) X-ray
sources detected in the first 37 months of data of the Monitor of
All-sky X-ray Image/Gas Slit Camera (MAXI/GSC). To achieve the best
sensitivity, we develop a background model of the GSC that well
reproduces the data based on the detailed on-board calibration. Source
detection is performed through image fits with a Poisson likelihood
algorithm. The catalog contains 500 objects detected with
significances of s_D,4-10keV_>=7 in the 4-10keV band. The limiting
sensitivity is 7.5x10^-12^erg/cm2/s ( 0.6mCrab) in the 4-10keV band
for 50% of the survey area, which is the highest ever achieved in an
all-sky survey mission covering this energy band. We summarize the
statistical properties of the catalog and results from cross matching
with the Swift/BAT 70 month catalog (Cat. J/ApJS/207/19), the
meta-catalog of X-ray detected clusters of galaxies (MCXC;
Cat. J/A+A/534/A109), and the MAXI/GSC 7 month catalog
(Cat. J/PASJ/63/S677). Our catalog lists the source name (2MAXI),
position and its error, detection significances and fluxes in the
4-10keV and 3-4keV bands, the hardness ratio, and the basic
information of the likely counterpart available for 296 sources.
Description:
The second Monitor of All-sky X-ray Image/Gas Slit Camera (MAXI/GSC)
catalog is based on the 37 months of data obtained from 2009 September
23 to 2012 October 15. The data reduction procedure is essentially the
same as that used to produce the MAXI/GSC 7 month (2009 September 1 to
2010 March 31) catalog in Hiroi et al. (2011, Cat. J/PASJ/63/S677).
