The analysis includes identification of spectral states based on hardness ratio and fitted spectral parameters, identification of timing properties of the corresponding state and comparison of the spectral and timing properties of different X-ray binary systems with that observed from earlier mission like RXTE and contemporary mission like NuSTAR. Within the calibration and systematic uncertainties, the high energy LAXPC spectra, in the energy range 15.0-50.0 keV, shows significant improvement over RXTE spectra in the similar energy range. Along with its unprecedented timing capabilities, LAXPC clearly shows significant improvement in understanding the accretion and radiation mechanism during spectral state transition in X-ray binaries which I shall discuss in my talk. |
