The Covering Factor of Quasar Broad Absorption Line Clouds
Abstract
In this Letter we show that the greater strength of N V line emission in BALQSOs, compared to "normal" QSOs, can be explained by a range of covering factors for the BAL material in QSOs, without recourse to orientation-dependent line emission or requiring that BALQSOs are an unusual subset of all QSOs.
