Since about 2 years I am coordinating this community engagement effort with an amazing team. Please check out the dedicated Data Challenge website (which I created and maintain). The Nancy Grace Roman Space Telescope (Roman, formally WFIRST) Exoplanet Imaging Data Challenge and Tutorial Suite are for exoplanet scientists who are interested in learning the art and science of high contrast imaging of exoplanetary systems. Roman's Coronagraph Instrument (formally CGI), with a possible Starshade rendezvous, is the only exoplanet imaging instrument planned for flight in the next decade.
The Data Challenge material was an excellent way to become familiar with the intricacies of the first spaceborne high contrast exoplanet imaging mission, as a pathfinder to future flagship missions. The CHALLENGE is now OVER but please, see our Timeline, play with the Data, check our Tutorial, Events and "Final Jamboree" videos with the winners/prizes!
On April 30th, we had organized a 3 ½ hour "Final Jamboree" event, we presented the challenge, its organization, summarized how the data were simulated and showed our in-house analysis for planet c.
We explained which metrics were applied to the participants' entries to rank them. Finally, we announced the winners/prizes and discussed the lessons learned, the the legacy tutorial as well as heard the 3 finalist teams give their feedback!
