We include all spin correlations and interferences, the bottom quark mass, and finite top width effects in the matrix element calculation. We study properties of the radiated gluons and implications for top mass measurement.4 pages including 3 figures, Latex, uses sprocl and epsfig; talk presented at the International Workshop on Linear Colliders, Sitges, Spain, April 28-May 5, 1999High Energy Physics - Phenomenologytext
