Fig. A.2.
UV fluxes as a function of orbital phase for the epochs 1995 (left), 1992 (middle) and 1988 (right). Each line flux is normalized by the average value of the line for the given epoch. The significantly weaker modulation in 1988 compared to 1992 and 1995 is evident, as is the large cycle-to-cycle dispersion over time in the N V emission flux of 1995.
