The total field of view of the array will be 25 arc minutes. The spectral resolution of 200 eV (at 6 keV), combined with the large collecting area, provides good opportunities, for example, for time-resolved iron line spectroscopy (6.4-6.9 keV). Potential observing programmes include stellar coronae, molecular clouds, cataclysmic variables and X-ray binaries; accretion discs and coronae of neutron stars and black hole candidates; supernova remnants, active galactic nuclei, clusters of galaxies and the diffuse cosmic X-ray background.   The US Spectrum-X-Gamma Coordination Facility - Spectrum-X-Gamma (SXG) is an international high-energy astrophysics observatory which is being built under the leadership of the Russian Space Research Institute (IKI). The US SXG CF supports the US astronomical community in obtaining information about SXG, proposing for and making SXG observations, and performing archival research using the SXG archive.
