Compilation of the nature of objects |

The physical nature of objects is collected from the literature and from the surveys loaded in HyperLeda. Before 2005, this information was directly stored in a homogenized parameters table where the best assigment was stored. A suposedly better estimate was replacing the previous one, and history information was lost. Therefore, the source of the classification before that time is given under the reference 88, and precise origin cannot be tracked.
