An X-ray binary (XRB) system is a semidetached binary system that contains a normal star or white dwarf donor and a neutron star (NS) or black hole (BH) accretor. Through processes such as Roche lobe overflow, winds, or circumstellar disc interaction, material streams down into an accretion disc surrounding the central object. At the inner radii of the accretion disc, there is enough viscous heating for the material to emit X-rays.

We observed the low-mass X-ray binary Sco X-1 for 12 nights simultaneously using the Rossi X-Ray Timing Explorer and the Otto Struve Telescope at McDonald Observatory at 1-s time-resolution. This is among the most comprehensive simultaneous X-Ray/optical data sets of Sco X-1. Evidence of reprocessing was observed in the form of nine positive, near-zero lag peaks in the cross-correlation function, eight of which were relatively small, and took the shape of piecewise exponential functions.
