Above ∼1800 Å the spectrum consists of a number of continua blanketed by numerous absorption lines (Labs & Neckel 1972), mostly produced by the upper photosphere.

On the one hand UV diagnostics imply a hot layer with only small temperature fluctuations, as expressed in static semi-empirical 1-D models like, e.g., FAL A, VAL C ([\astroncite Fontenla et al.1993]; [\astroncite Vernazza et al.1981]).
