Scientific paper

Faulkner's (1977) period fitting formulas are employed to derive mass estimates for double mode or beat Cepheids. Luminosity values used in the calculations assume the standard Hyades distance modulus, (m-M)o = 3.03. Attention is given to a Fourier analysis, whereby techniques which are similar to power spectrum analysis are applied to the least squares method in order to plot discrepancies in the observed stellar masses.
