» Timing analysis with INTEGRAL
Presenter: Victoria Grinberg
INTEGRAL is one of the few instruments capable of detecting X-rays above 20 keV. It is therefore in principle well suited for studies of X-ray variability in this regime. Because INTEGRAL uses coded mask instruments for its imaging, the reconstruction of light curves of X-ray sources is highly non-trivial. We present results from the comparison of two commonly employed algorithms, which measure flux from mask deconvolution and from calculating the pixel illuminated fraction (ii_light). Both methods agree well for timescales above about 10s, the highest time resolution for which image reconstruction is possible. For higher time resolution, ii_light produces in meaningful results, although the overall variance of the lightcurves is not preserved.
