This model grid contains 228,016 synthetic red supergiant explosion (Type II supernova) models. Time evolution of spectral energy distributions from 1 Angstrom to 50,000 Angstrom (100 frequency bins in a log scale) up to 500 days after explosion is computed in each model. We provide light curves for the filters of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST), Zwicky Transient Facility (ZTF), Sloan Digital Sky Servey (SDSS), and the Neil Gehrels Swift Observatory, but light curves for any photometric filters with any extinctions at any redshifts can be constructed based on the synthetic spectral energy distributions. We also provide bolometric light curves and photosphere information such as photospheric velocity evolution. The parameter space covered by the model grid is five progenitor masses (10, 12, 14, 16, and 18 solar mass at the zero-age main sequence, solar metallicity), ten explosion energies (0.5e51, 1.0e51, 1.5e51, 2.0e51, 2.5e51, 3.0e51, 3.5e51, 4.0e51, 4.5e51, and 5.0e51 erg), nine 56Ni masses (0.001, 0.01, 0.02, 0.04, 0.06, 0.08, 0.1, 0.2, and 0.3 solar mass), nine mass-loss rates (10^-5.0, 10^-4.5, 10^-4.0, 10^-3.5, 10^-3.0, 10^-2.5, 10^-2.0, 10^-1.5, and 10^-1.0 Msun/yr with a wind velocity of 10 km/s), six circumstellar matter radii (1e14, 2e14, 4e14, 6e14, 8e14, and 1e15 cm), and ten circumstellar structures (beta = 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0). 56Ni is assumed to be uniformly mixed up to the half mass of a hydrogen-rich envelope.


This model grid is constructed by the one-dimensional multi-frequency radiation hydrodynamics code STELLA (Blinnikov et al. 1998, ApJ, 496, 454; Blinnikov et al. 2000, ApJ, 532, 1132; Blinnikov et al. 2006, A&A, 453, 229).
