Upper panel: flux in the N V λ1238.8 line, integrated over the velocity range –3 and 31 km s⁻¹, persistently absorbed in visits A_fuv (blue), B_fuv (green), and C_fuv (red). Lower panel: Flux integrated over the complementary of the absorbed range within –100 to 100 km s⁻¹. Fluxes are normalized using the stable reference spectra in each visit (see text) and plotted as a function of time relative to 55 Cnc e transit.
