  "abstract": "<p>Gravitational waveforms from 1824 fiducial and detailed electron capture simulations, sampled at 65535 Hz. The file is in HDF5 format, using the flags {dtype=\"f4\",compression=\"gzip\",shuffle=True,fletcher32=True}. Each group is contained in the \"waveforms\" top-level group and is named with the \"A\" and \"omega_0\" values from Equation 5 and the EOS. In each sub-group is a dataset containing timestamps in seconds (t=0 is core bounce) and a dataset containing the strain multiplied by the distance in centimeters. The values of A in kilometers, omega_0 in radians/s, and the EOS are stored as attributes of each group.</p>\n\n<p>In addition, the Ye(rho) profiles are stored in the \"yeofrho\" top-level group. Each sub-group is labeled by the EOS used to generate the profile.</p>\n\n<p>Finally, select reduced data is stored in the \"reduced_data\" top-level group. The following quantities are each stored as a 1824-element array, where elements of the same index from different datasets correspond to the same 2D simulation.</p>\n\n<p>A(km) -- differential rotation parameter in Equation 5<br>\nD*bounce_amplitude_1(cm) -- The minimum\u00a0of the first (negative) GW strain peak, multiplied by distance.<br>\nD*bounce_amplitude_2(cm) -- The maximum of the second (positive) GW strain peak, multiplied by distance.<br>\nEOS -- the equation of state used in the simulation<br>\nMbarICgrav(Msun) -- gravitational mass of the inner core, averaged over time after core bounce<br>\nMgrav1_IC_b(Msun) -- gravitational mass of the inner core at bounce<br>\nMrest_IC_b(Msun) -- rest mass of the inner core at bounce<br>\nSNR(aLIGOfrom10kpc) -- signal to noise ratio of the GW signal, assuming a distance of 10kpc and aLIGO sensitivity<br>\nT_c_b(MeV) -- central temperature at bounce<br>\nYe_c_b -- central electron fraction at bounce<br>\nalpha_c_b -- central lapse at bounce<br>\nbeta1_IC_b -- ratio of rotational kinetic to gravitational potential energy of the inner core at bounce<br>\nfpeak(Hz) -- frequency of the post-bounce GW oscillations<br>\nj_IC_b() -- angular momentum of the inner core at bounce<br>\nomega_0(rad|s) -- initial (pre-collapse) rotation rate used in Equation 5<br>\nomega_max(rad|s) -- maximum rotation rate achieved outside of 5km<br>\nrPNSequator_b(km) -- radius of the rho=10^11 g/ccm contour along the equator at bounce<br>\nrPNSpole_b(km) -- radius of the rho=10^11 g/ccm contour along the pole at bounce<br>\nr_omega_max(km) -- radius where omega_max occurs<br>\nrho_c_b(g|ccm) -- central density at bounce (not time averaged)<br>\nrhobar_c_postbounce(g|ccm) -- central density time averaged after bounce<br>\ns_c_b(kB|baryon) -- central entropy at bounce<br>\nt_postbounce_end(s) -- time of the end of the postbounce signal (t=0 is core bounce)<br>\ntbounce(s) -- time of core bounce (t=0 is the beginning of the simulation)<br>\n\u00a0</p>",
