Abstract
We present results of spectral analysis of Ginga data obtained during the decline phase after the 1989 outburst of GS 2023+338 (V404 Cyg). O ur analysis includes detailed modeling of the effects of X-ray reflect ion/reprocessing. We have found that (1) the contribution of the repro cessed component (both continuum and line) corresponds to the solid an gle of the reprocessor as seen from the X-ray source of Omega approxim ate to (0.4-0.5) x 2 pi, and (2) the reprocessed component (both line and continuum) is broadened (''smeared'') by kinematic and relativisti c effects, as expected from the accretion disk reflection. We discuss the constraints these results give on various possible system geometri es.
