  We present a new series of supernova neutrino light curves and spectra
calculated by numerical simulations for a variety of progenitor stellar masses
(13-50Msolar) and metallicities (Z = 0.02 and 0.004), which would be useful for
a broad range of supernova neutrino studies, e.g., simulations of future
neutrino burst detection by underground detectors, or theoretical predictions
for the relic supernova neutrino background. To follow the evolution from the
onset of collapse to 20 s after the core bounce, we combine the results of
neutrino-radiation hydrodynamic simulations for the early phase and
quasi-static evolutionary calculations of neutrino diffusion for the late
phase, with different values of shock revival time as a parameter that should
depend on the still unknown explosion mechanism. We here describe the
calculation methods and basic results including the dependence on progenitor
models and the shock revival time. The neutrino data are publicly available
electronically.
