from NASA  From: NASA/Goddard Space Flight Center To: Drew
Freeman Research Facility  We have detected X-ray emission from
the Galactic Center region, from a source located approximately
4 kiloparsecs away, in an area in the sky just below the
constellation Scorpius. We believe this source is either a black
hole or a neutron star. The Rossi X-Ray Timing Explorer (RXTE)

need you to collect, graph, and analyze the data to help to
determine whether or not light-curves can accurately identify
the source. When our spectru
