A 4 Gy-old asteroid family and the big void in the asteroid Main Belt

These data have been used to discover a family of asteroids as old as our Solar System and also a peculiar section of the Main asteroid Belt that lacks small asteroids. These features allowed us to identify the original asteroids accreted from the protoplanetary disk. Here we provide all the source codes and the data-files to build a database of asteroid physical properties, which we used for this project. Data coming from different surveys of asteroid physical properties are included here. They have been obtained from the original publications (e.g. Masiero et al. 2011. ApJ 741 68). References to these original publications can be found in the paper related to this dataset: Delbo, Walsh, Bolin, Avdellidou, Morbidelli. 2017.
