Amol’s suggestion for models to look at:
1. Livermore (energies have a smooth time variation) 2. Garching early time (accretion phase) 3. Garching late time (cooling phase) 4. Basel (smooth monotonic time variation for energies and fluxes)
Flux File Format
Compatible with GLoBES
Seven columns and 501 lines with equidistant energies
Energy / Phi_nue / Phi_numu / Phi_nutau / Phi_nuebar / Phi_numubar / Phi_nutaubar
Energy should be in GeV Flux units: per second per cm^2 (per energy bin). The flux should be for a supernova at 10 kpc.
I suggest 0 to 0.1 GeV as the standard energy range for the flux file (the binning in 500 bins will be finer than any experiment energy resolution).
Files are differential energy spectra only: there should be one file per time slice, plus one file with the spectrum integrated over time.
One-line comments beginning with # and ending with "\n" can be included for notes.
Proposed filename format: fluxname-time-timebinsize.dat

Luminosities and Mean Energies
Here are files of the luminosities and mean energies. Other than the Garching case the functional form of the spectra is unknown.

In the absence of profiles from the simulations here are some density profiles used in Kneller, McLaughlin and Brockman. Three 1D models are provided ranging from a weak explosion (model 6e35) through something canonical (model 8e35) and then up a strong explosion case (model 2e36). For compactness the data is in 'carpet' format: i.e.
i.e. each column gives rho(r) at some fixed time. There are 750 rows, 78 columns in each file. The units are: [r] is in cm, [t] is in seconds. [rho] is in g/cm^3. Y_e can be set to 1/2. There are two issues with the profiles you should be aware of: the profiles have deficiencies in the inner regions because neutrino cooling was not included in the simulations, the shocks are 'soft'. To compensate for these problems the profiles between the proto-neutron star and a radius of r ~ few hundred km should be replaced by a parametric form such as a double power-law
rho = C1 r^n1 + C2 r^n2
The parameters C1, C2, n1, n2 are determined by the requirement that the parametric form be continuous and have continuous derivative at the boundaries with the rest of the data. The soft shocks can either be steepened by hand or you should use a value of theta_13 no larger than 1°.
Lastly, this data is provided solely for the purpose of this study.
