摘要：

Global (source- and direction-averaged) and local (direction-averaged) Doppler-profile escape factors for plane-parallel sources are calculated and tabulated for a range of line-center optical thicknesses tau(0), and are compared with published or derived small- and large-tau(0) approximations. Integration (averaging) over the local escape factor provides a consistency check on both the global and local evaluations. (C) 2000 Elsevier Science Ltd. All rights reserved.
