The Carrington maps are made in He I 584 A (20,000 K), O V 629 A (250,000 K), Mg IX (1 million K) and Fe XVI (2 million K) and more recently Mg X (1.5 million K). Each map is made up of daily 4' wide meridian scans. 28 scans make up one solar rotation, shown as a rectangular map representing the full Sun. Thus, the maps cover the range N90 to S90 (ordinate) and one full rotation or complete longitude coverage (360 degrees).
