A new, computationally- and statistically-efficient algorithm, the Fast$\chi^2$ algorithm, can find a periodic signal with harmonic content inirregularly-sampled data with non-uniform errors. The algorithm calculates theminimized $\chi^2$ as a function of frequency at the desired number ofharmonics, using Fast Fourier Transforms to provide $O (N \log N)$ performance.The code for a reference implementation is provided.
