Trends in Astronomical Data from the Four College Automated Photometric Telescope (FCAPT)

We analyze differential Strömgren 𝑢𝑣𝑏𝑦 observations from the Four College Automated Photometric Telescope (FCAPT) in Washington Camp, AZ.   We explore the relationship between the Strömgren indices and the surface elemental composition of the star.   Mathematical techniques used include the Lomb-Scargle periodogram, clustering, and regression analysis.  This is a work in progress and we present preliminary results.
