This article introduces S-parameter network flow diagrams and how they may be manipulated to solve real-world problems. Knowledge of network flow diagrams is a prerequisite to interpret the 12-term ...

Analysis of luminosity functions is included within the HR diagram algorithm as a special case. Areal density analysis of HR diagrams is acceptably fast because we handle stellar evolution via ...

An objective process for estimation of star cluster parameters from Hertzsprung–Russell (HR) diagrams is introduced, with direct inclusion of multiple stars, a ...
