A total of 255 grids of 368064 simulations each are summarised in tables. Only bound double neutron star systems are logged. The filenames are in the following form: 368k_m__ecap__alpha_.txt For example, for a metallicity of 0.02, electron-capture supernova kick velocity dispersion of 26 km/s, and common-envelope ejection efficiency of 0.5, the filename is: 368k_m_0.02000_ecap_26.00_alpha_0.5000.txt 30 grids employed a simplified prescription for the envelope binding energy - lambda=0.5 instead of the Claeys+14 prescription. The filenames for these are in the form: 368k_lambda_0.5_m__ecap_26.00_alpha_.txt Each table contains the following: Primary_ZAMS_Mass - initial mass of the heavier star Mass_Ratio - initial mass of the lighter companion divided by the initial mass of the heavier star Initial_Period - initial orbital period in days N_CEE - number of common envelope episodes Star1_Type_1st_CE - star 1 type entering the first common envelope Star2_Type_1st_CE - star 2 type entering the first common envelope Star1_Type_2nd_CE - star 1 type entering the second common envelope Star2_Type_2nd_CE - star 2 type entering the second common envelope Star1_Type_3rd_CE - star 1 type entering the third common envelope Star2_Type_3rd_CE - star 2 type entering the third common envelope Star1_Type_4th_CE - star 1 type entering the fourth common envelope Star2_Type_4th_CE - star 2 type entering the fourth common envelope N_AIC - number of accretion-induced collapse events during the binary evolution (maximum of 1) N_ECSNe - number of electron-capture supernovae during the evolution N_Type_I_SNe - number of Type Ib/c supernovae during the evolution N_Type_II_SNe - number of Type II supernovae during the evolution NS_Mass_1 - mass of the neutron star formed from the initially heavier star NS_Mass_2 - mass of the neutron star formed from the initially lighter star DNS_Formation_Age_in_Myr - system age at which the second neutron star formed DNS_P_in_Days - orbital period in days when the second neutron star formed DNS_Eccentricity - eccentricity when the second neutron star formed DNS_Separation_in_Rsun - separation when the second neutron star formed DNS_Delay_Time_in_Myr - sum of system age at which the second neutron star formed and time to merge by orbital decay because of gravitational waves The star types as defined in binary_c: 0: LOW_MASS_MS / LOW_MASS_MAIN_SEQUENCE 1: MS / MAIN_SEQUENCE 2: HG / HERTZSPRUNG_GAP 3: GIANT_BRANCH / FIRST_GIANT_BRANCH 4: CHeB / CORE_HELIUM_BURNING 5: EAGB / EARLY_ASYMPTOTIC_GIANT_BRANCH 6: TPAGB / THERMALLY_PULSING_ASYMPTOTIC_GIANT_BRANCH 7: HeMS / NAKED_MAIN_SEQUENCE_HELIUM_STAR 8: HeHG / NAKED_HELIUM_STAR_HERTZSPRUNG_GAP 9: HeGB / NAKED_HELIUM_STAR_GIANT_BRANCH 10: HeWD / HELIUM_WHITE_DWARF 11: COWD / CARBON_OXYGEN_WHITE_DWARF 12: ONeWD / OXYGEN_NEON_WHITE_DWARF 13: NS / NEUTRON_STAR 14: BH / BLACK_HOLE 15: MASSLESS_REMNANT
