This paper presents preliminary results of the correlated x-ray and optical behavior of Sco X-1 based on two years of data. The optical data was obtained during 20 nights of observing time using the Cerro Tololo InterAmerican Observatory 1 meter Yale telescope. These measurements were obtained simultaneously with data collected by a BATSE Spectroscopy Detector (SD) on the CGRO. The gain of this SD was adjusted to provide measurements in the energy bandpass 8–16 keV. The intent of our study is to quantify the correlated x-ray and optical behavior of Sco X-1 over a variety of time frames. Here we discuss the data sets to be employed in that study. We also discuss the method used to reduce the BATSE SD x-ray data. Some preliminary simultaneous x-ray and optical light curves are presented and their correlated behavior over time frames from tens to a few hundred seconds is briefly discussed. © 2000 American Institute of Physics.
