Abstract
Global (source- and direction-averaged) and local (direction-averaged) Dopp ler-profile escape factors for plane-parallel sources are calculated and ta bulated for a range of line-center optical thicknesses tau(0), and are comp ared with published or derived small- and large-tau(0) approximations. Inte gration (averaging) over the local escape factor provides a consistency che ck on both the global and local evaluations. (C) 2000 Elsevier Science Ltd. All rights reserved.
