Time evolution of the normalized electron neutrino lepton number

Time evolution of the electron neutrino lepton number (ELN) normalized to its average [(N_νe - N_ν̅e)/<(N_νe - N_ν̅e)>] on a Mollweide map of the progenitor's emission surface for the three 15 M_sun supernova models with different rotational velocities. See Paper 2 for more details.

Time evolution of the relative IceCube detection rate

Time evolution of the relative IceCube detection rate [(R-<R>)/<R>] on a sky-plot of observer directions for the three 15 M_sun supernova models with different rotational velocities. The rate has been computed for the un-oscillated electron antineutrino flux (i.e., in the absence of flavor conversions). See Paper 1 for more details.

Angle dependent neutrino emission properties

Luminosity (erg/s), mean energy (MeV), and mean squared energies (in MeV²) of ν_e, ν̅_e, and ν_x for the three 15 M_sun supernova models with different rotational velocities. The neutrino properties have been projected and recorded as seen by a distant observer, and mapped to a spherical grid consisting of angular zones in θ (inclination angle) and ϕ (azimuthal angle). The properties have been extracted from the simulation grid at a radius of 500 km. See Paper 2 for more details.

Each files contain post-bounce time (s), inclination angle (θ), azimuthal angle (ϕ), and the neutrino property at hand, recorded in four columns respectively. At each post-bounce time, the neutrino properties are recorded across all angular zones, ordered firstly by increasing θ values, and secondly across all ϕ coordinates.

The following (θ,ϕ) directions of the simulation grid correspond to the ones with strong, intermediate, and weak signal modulation (see Figs. 2-4 of Paper 2):

- non-rotating: strong: (3.0166, 0.19636), intermediate: (2.1242, 1.0889), weak: (1.6601, 1.6601)
- slowly rotating: strong: (0.58905, -2.374), intermediate: (0.66045, -0.33914), weak: (1.0174, 1.8743)
- fast rotating: strong: (3.088, -0.62474), intermediate: (1.5886, 0.94606), weak: (2.2312, 1.91)


Spherically averaged neutrino emission properties

Spherically averaged luminosities (erg/s), mean energies (in MeV), and mean squared energies (in MeV²) [the energies are measured for the number flux] of the aforementioned models from Summa, A., et al., ApJ, 852, 28 (2018):
