# FAMILIES_TABLE.txt # Families: a summary of ages, albedos, parent body sizes, escape velocities, etc. # Miroslav Broz (miroslav.broz@email.cz), Aug 31st 2014 # 1. designation # 2. "traditional" name # 3. cutoff velocity v_cutoff (m/s) # 4. number of members # 5. mean geometric albedo p_V, a letter "w" denotes we used WISE data to determine the median albedo (and improve membership) # 6. taxonomic classification, or a proxy of it inferred from SDSS colours # 7. parent body size (km) from SFD, an additional "c" letter indicates that we prolonged the slope down to zero D # 8. PB size from SPH simulations (monoliths, Durda et al. 2007) # 9. largest fragment LF/PB volumetric ratio (our estimate and also the value inferred from D_Durda - the range is given in this case) # 10. escape velocity (m/s) # 11. SFD slope_1 (for larger D) # 12. slope_2 (for smaller D) # 13. value of the C parameter (expressed in 10^-4 AU units): 0.2 H = log_10(|a-a_c|/C) (Vokrouhlicky et al. 2006) # 14. age (Gyr) # 15. +- # 16. uncertainty # 17.
