| Abstract: | HAKUCHO observation of Cyg X-2 over 40 days did not show a correlation between the hardness ratio and the intensity predicted for dwarf X-ray sources. The energy spectrum in the range 0.3 – 20 keV was found to deviate from the thermal bremsstrahlung spectrum below 2 keV. The X-ray spectrum can be accounted for in terms of the comptonization of blackbody radiation emitted from teh neutron star surface and the accretion disk. |
