Hess diagram with data from SDSS b>80 degree
A Hess diagram plots the relative density of occurrence of stars at differing color–magnitude positions of the Hertzsprung–Russell diagram for a given galaxy or resolved stellar population. The diagram is named after R. Hess who originated it in 1924.[1] Its use dates back to at least 1948.[2]
Hess diagrams are widely used in the study of discrete resolved stellar systems in and around the Milky Way - specifically, in the analysis of globular clusters, satellite galaxies, and stellar streams.
