BeppoSAX 2-10 keV Survey
Listed in IVOA Registry (Virtual Observatory)
This catalog presents the results of a 2 - 10 keV BeppoSAX survey based on 140 high galactic latitude Medium Energy Concentrator Spectrometers (MECS) fields, 12 of which are deep exposures of ``blank'' parts of the sky.
Description
The limiting sensitivity is 5 x 10<sup>-14</sup> erg/cm<sup>2</sup>/s (or mW/m<sup>2</sup>) where about 25% of the Cosmic X-ray Background (CXB) is resolved into discrete sources.
The log N - log S function, built with a statistically complete sample of 177 sources, is steep and in good agreement with the counts derived from ASCA surveys. This database was created by the HEASARC in December 2000 based upon <a href="cdsarc.cds.unistra.fr/ftp/cats/J/A+A/362/799">CDS Catalog J/A+A/362/799</a>. This is a service provided by NASA HEASARC .
