Shenhar, Ben; Guttman, Or; Waxman, Eli

We release datasets containing electron energy deposition and electron spectra in kilonovae ejecta, for a wide range of parameters, as described in [1].

We include 2 datasets: `deposition_data` and `electron_spectra`

## Deposition Data

`deposition_data` includes electron energy release and deposition for our entire parameter space considered. Data attached for each parameter set contains:

`time` - timestamps of simulation in units of [sec].

`Q_dot` - total electron energy release in units of [erg/s/g]

`f_inst` - instantaneous fractional deposition, calculated according to Eq. (9) in [1]

`time_dep` - timestamps of electron energy deposition calculation

`Q_dep` - electron energy deposition in units of [erg/s/g], calculated according to Eq. (6) in [1]

## Electron Spectra

`electron_spectra` includes energy spectra of electrons for a representative set of our parameter space. Data attached for each parameter set contains:

`isotopes_table` - csv containing table of all 3821 isotopes included in nucleosynthesis calculations

`time` - timestamps of simulation in units of [sec].

`Q_dot` - total electron energy release in units of [erg/s/g]

`density` - ejecta density in units of [g/cm^3]

`Egrid` - energy grid on which electron spectra was calculated, in units of [eV]

`electron_spectra_CDF` - cumulative distribution function of the energy release electron spectra (CDF of E dN_dot/dE , see Eq. (7)), calculated against `Egrid`

`Y_abundances` - time-dependent abundances of 3821 isotopes

`Y_energy_release` - time-dependent electron energy release for all 3821 isotopes, in units of [erg/s/g]
