Example continuum-corrected spectra from ISIS (top), and FLAMES (bottom). Grey shaded regions indicate the wavelength ranges used when cross-correlating the spectra with theoretical templates to measure radial velocities. Note that some of the emission lines visible in the FLAMES spectra are caused by the background nebula.
