Emulsion data for electron neutrino appearance studies

<p>This dataset was extracted from the official OPERA data repository and it contains all the emulsion data information for 19 electron neutrino candidates, identified after an extensive analysis that includes data from both electronic detectors and nuclear emulsion films after their digitization with fully automated optical microscopes. The OPERA experiment was able to distinguish all three types of neutrinos, including electron ones.

In total, 35 electron neutrino events were found in the complete data sample. Here a subsample of 19 electron neutrino interactions is reported.</p><p>This data record contains in particular the information of the neutrino interaction vertices including all the emulsion tracks produced in the observed interactions. The location of the neutrino interaction and the measurement of the trajectories of all the particles produced is the final step of the event analysis, after the identification of the neutrino interaction bricks done with the electronic detector data.
