Abstract:We report the results of simultaneous optical/X-ray observations of X1822-371 at 0.1 second time resolution. The preliminary analysis finds no correlation between the optical/X-ray light curves. We aim to constrain the vertical structure and radius of the accretion disc.Deceased Feb. 13, 2005
Keywords:Low-mass X-ray binaries  X1822-371
