Abstract : Programs were compiled to compare experimental data with mathematical models with respect to magnetic activity. Micropulsations were investigated and programs were written to compute the eigenperiod and modulus of decay, so the predicted results could be compared with experimental observations. This was a particularly difficult problem, because the dispersion relationship was a complex transcendental equation, and required a 2part fit. The complex function was mermorphic with respect to its complex arguments, and so the CauchyRiemann conditions were applicable. The secular equation was expanded in a Taylor Series, and then the equation was cast in a form immediately amenable to the numerical analysis. The programs were written and can now be easily reformated, suitable for production basis on the CDC 6600. (Author Modified Abstract)
