TL;DR: In this article, the authors present a self-consistent empirical model for several plasma parameters in the extended solar corona above a polar coronal hole, derived from observations with the SOHO Ultraviolet Coronagraph Spectrometer (UVCS/SOHO) during the period between 1996 November and 1997 April.
