Data for Escaping Binary Black Holes That Will Merge within 14 Gyr from 257 models simulated for MOCCA-Survey Database II

Each line in the file escaping-merging-BBH-survey2.dat represents data for an escaping binary black hole (BBH) from the test MOCCA Survey Database II. The details of the survey and simulation methodology are described in Hypki et al. (2022): https://ui.adsabs.harvard.edu/abs/2022MNRAS.517.4768H/abstract and Maliszewski et al. (2022): https://ui.adsabs.harvard.edu/abs/2022MNRAS.514.5879M/exportcitation. This dataset has been utilized for the manuscript currently in preparation by Yuetong, Askar et al.
