The Solar Disks Spectrum atlas itself can be found via this link. A print screen is shown below
Some nice features:
By clicking on "##" of interesting wavelengths you get for all lines more details aswell as a personal ranking.
By clicking on the "eye" 1.1, 1.2,...of interesting wavelenghts you get each time more specific line on interest. When clicking on it you go to the immediate wavelength and image
By clicking on spectrum++ or diagram++ you switch between the spectrumline or diagram.
This is great work by the team and will be an extra tool to use .. to find interesting lines but also to compare the images.
