The validation and recovery of periodic signals in radial velocity data, especially low amplitude signals, is being complicated by the inherent stellar variations due to stellar activity. Using the time-series of high-resolution HARPS-N spectra of stars as well as the Sun, we are developing a new least-squares deconvolution method to determine at the same time a precise radial velocity and an independent measurement of the instantaneous line-of-sight magnetic flux on the visible stellar hemisphere. We present the new method as well as some first results. |
