Time evolutions of the event rates (top panels) and cumulative numbers of events (bottom panels) for the 15 ﹩{M}_{\odot }﹩ progenitor model. The upper half of each panel shows the results for the normal mass hierarchy, while the lower half presents those for the inverted mass hierarchy. Colors specify the neutrino detectors. We consider ﹩{\nu }_{e}﹩ for DUNE (dotted line) and ﹩{\bar{\nu }}_{e}﹩ for other detectors (solid lines).
