Panel a): intensity image in He i spectral line. Each vertical column in the image is corresponding to the average of the spectra over the wavelength dimension for a given x position (i.e. exposure). Panel b): given exposure, corresponding to the white line in panel a), consisting of 143 spectra along the y direction. Panel c) is a spectrum recorded along the white line in panel b).
