Abstract

X-ray spectral parameters were determined for WZ Sge observed with the ROSAT PSPC. The raw data were fitted with various spectral models and the best fit spectral models are found to be that of Raymond-Smith and Thermal Bremsstrahlung. The best fit temperature was estimated to be kT similar to 2.17 keV while the column density was found to be N(H)similar to 2.8x10(20) cm(-2). The estimated 0.1-2.4 keV flux was in the range of log F=-12 ergs cm(-2) s(-1).
