We release outflow data extracted at a fixed coordinate sphere with radius 300
G/c^2 Msun (= 443 km). Only material unbound according to the geodesic
criterion is considered to be part of the dynamical ejecta.

Included data:

* `Table2.txt`: Table 2 of the paper in machine readable format

* `tabulated_nucsyn.h5`: nucleosynthesis yields from pre-computed parametrized
  trajectories. The first three indices of each dataset are Ye, entropy, and
  expansion timescale tau. For example `Y_final[iYe, ientr, itau, iiso]` gives
  the final abundance of isotope `iiso` with `A[iiso]` and `Z[iiso]` for a
  trajectory with initial Ye = `Ye[iYe]`, initial entropy `s[ientr]`, and
  expansion timescale `tau[itau]`.

* `[model].tar`: ejecta data for individual simulations. The naming convention
  is the same as in the paper.

For each model we provide:

* `outflow.txt`: angle integrated outflow rate and cumulated ejecta mass. Data
  are given in units with Msun = G = c = 1 (eg, the conversion factor for time to
  seconds is 4.9258e-6).

* `hist_entropy.dat`: histogram of the ejecta as a function of the entropy (in kb)

* `hist_vinf.dat`: histogram of the ejecta as a function of the asymptotic
  velocity (in units of c)

* `hist_ye.dat`: histogram of the ejecta as a function of the electron fraction Ye.

* `profile.txt`: time integrated ejecta profiles as a function of the polar angle.

* `hist_vinf_theta.h5`: histograms of the ejecta as a function of the
  asymptotic velocity and the polar angle.

* `hist_ye_theta.h5`: histograms of the ejecta as a function of the
  asymptotic velocity and the polar angle.

* `hist_ye_entropy_tau.h5`: histograms of the ejecta as a function of Ye,
  entropy, and expansion timescale tau.

Additionally we distribute:

* Initial data generated with LORENE and associated EOS tables.

* Parameter file used for each simulation

For the multidimensional histograms the indices are ordered as specified in the
file name, ie the file `hist_ye_theta.h5` tabulates the ejecta mass as a
function of Ye (first index) and polar angle theta (second index).
