We have been a bit busy organizing the data, but the final HARPS dataset from Red Dots is now available for downloads at
If you want make use of the data for scientific publications, remember that this is still preliminary, and that we welcome contributions and open discussions on this dataset. We mentioned the possibility of a second strong signal in Proxima’s RVs. Instead of forcing our conclusions into you, we let you take a look at all the observations and try to draw your initial conclusions (if you are new, we suggest using the systemic tool) For those with technical expertise in high resolution spectroscopy and science formats, you can access the ESO reduced files in the Proxima/Spectra folder, and the corresponding up-to-date radial velocities in Proxima/timeseries/.
Periodogram search on the ‘Red Dots 2017’ data set only. As in last year, the signal at ~11 days is significant in the new set, adding further robustness to the detection of Proxima b. This also implies we are likely to reach similar sensitivities on the other two stars (Barnard’s and Ross 154). Exciting. Combination with previous data might reveal additional signals, but these analyses will take more time and thinking. ...
