The first spectra obtained by HARPS are now publicly available at https://reddots.space/data/
We planned earlier releases, but weather conditions were not great. So far, we have collected 10 out of 22 possible epochs, which is not a great success rate. The data is organised as follows
In ‘Proxima/timeseries’, you will find the latest radial velocity measurements and the ‘historical’ data sets used in last year’s paper. They are provided as ‘night’ averages for simplicity. If you have never worked with time-series before, software packages such as Systemic should make your life easier. Check the community tools available here https://reddots.space/toolkit/
The files are regular text (ASCII files) and can be imported to analysis and plotting tools such as Excel, LibreOffice, gnuplot, etc.
The new data is showing interesting features when combined with previous ones. To avoid biasing you and our colleagues, we will refrain ourselves from commenting for now!
If you have opinions and/or things you would like to discuss about the time-series and the spectra, please do so in the comments to this post, or via social media (including the @RedDotsSpace (Facebook and/or Twitter) or hashtag #reddots. Photometry and comments on the other stars to follow soon!
