Abstract: Isophotes obtained by equidensitometry techniques from four exposures of the March 7, 1970 corona are used for derivation of intensity distributions along the equator, poles, streamers and dark ' gaps ' in the visible corona. The distributions differ from the van de Hulst curves for a maximum corona. The Kodaikanal measures agree well with the NRL measures of the outer corona made from a rocket coronagraph and together provide data from 1.2R0 to 8-ORo along the solar equator. Radial intensity gradients for different position angles and €he LudendorfF parameters obtained, characterize this corona as typical of the solar maximum.
