Four examples of highly asymmetric spectral profiles that are suggestive of Doppler-shifted emission peaks. The pink cross in the Hα wing images (to the left) marks the location of the full spectral profile shown in the top right (pink profile). The gray profile is a reference profile averaged over the full MiHI FOV. The spectral profiles are normalized to the intensity at the shortest wavelength of the reference profile. The vertical dashed yellow line marks the location of the λy diagram shown to the right.
