Representative PEPSI solar spectrum taken with the SDI telescope (x-axis is wavelength in Angstroms, y-axis is relative intensity). Each spectrum covers the wavelength range 382.2–914.6 nm without gaps with a sampling of 430 000 pixels at an average dispersion of 12 m pix −1. The different colors indicate the wavelength regions covered by the six cross dispersers.
