These data must be collected over multiple observation sessions, the Green Bank Telescope schedule is available at https://dss.gb.nrao.edu/schedule/public. Next observations are in about 15 hours - May 16 05:15 PT

Yes, these data will be publicly available soon. However, providing full random access to ~50TB is challenging for an academic project. If you have s3 or equiv to donate, or HDs you would like to fedex, please contact SETI@home. :)

Astronomical radio signals indicative of an engineered origin.. lots of electromagnetic energy in a narrow frequency range or a very narrow time window. The latter is also produced by pulsars, but there's only one known pulsar in/near the Kepler field and, generally speaking, pulsars to not contribute a significant background for such searches because they are so rare - only ~2000 are known.
