This article analyzes a scheme for frame decompositions that is called Ξ±-expansion. In this scheme, the choice of a parameter Ξ± adequate to a given frame is a central point. We develop a theory that helps choosing the parameter Ξ± and also suggests algorithms for obtaining the Ξ±-expansions. The metho
