Example He I 1083 nm line profiles that show emission. Left: line profiles. Right: local continuum normalized intensity in the red wing of He I 1083 nm, with the locations of the profiles left indicated with squares of the same color as the profile. The line profiles are taken from the entire time series, not just from the timestep shown in the right-hand panel. The labeled line profiles are discussed in Sects. 5.4–5.6.
