Period04 - Homepage Period04 is a computer program especially dedicated to the statistical analysis of large astronomical time series containing gaps The program offers tools to extract the individual frequencies from the multiperiodic content of time series and provides a flexible interface to perform multiple-frequency fits
Period04: Statistical analysis of large astronomical time series Period04, written in Java C++, supports the SAMP communication protocol to provide interoperability with other applications of the Virtual Observatory It is a reworked and extended version of Period98 (Sperl 1998) and PERIOD PERDET (Breger 1990)
Period04 – Periodicities in Light Curves and Fourier Transforms This tells Period04 to subtract the sinusoid from the original light curve and calculate the FT of what’s left over It will select the highest amplitude peak, and ask you if you want to use it
