Spectral profiles of 55 Cnc FUV lines, uncorrected for their spectral shifts. Vertical dashed lines correspond to the rest wavelength of the stellar lines in the expected star rest frame. Each row corresponds to a stellar line. First to third columns correspond to visits A_fuv, B_fuv, and C_fuv, respectively.Spectra in exposures 0 to 4 are indicated in blue, cyan, green, orange, and red, respectively (the first visit has no exposure 4).
