Quantifying the shapes of Cepheid variable star light curves is a technique that has been in use for the past several decades. Work to date has been primarily done for a few stars observed at a single site or by compiling the data for many stars from various sites. The availability of photometry from the Hipparcos satellite presents the opportunity to utilize a homogenous data set to calculate the Fourier parameters. Light curves of 135 classical Cepheids observed by Hipparcos were decomposed. The Hipparcos periods were used and the light curves were categorized into four groups based on the completeness of phase coverage. There were 28 ...
