Metadata description

The ssoBFT is a very large table containing all the property values of all the SSOs. However, many fields are empty because there are no estimates of certain properties for many SSOs, giving a fill factor of only ~16% . The fields of the ssoBFT are composed of the flattening of all the data contained in the ssoCard. The following tables provide an overview of the metadata of all properties.

Usage and citation

The ssoBFT table is the result of a long and meticulous work of reading scientific articles (more than 3000) to extract the properties of the SSOs that compose the table. For any use of the table, we ask the citation of the article: Berthier et al., 2023.

The content of the ssoBFT would not exist without the scientific work of all the authors who have determined and published the properties of the SSOs. Whenever possible, please publish the bibliographic references of the articles from which the SSO properties you are using are derived. For that, you have to extract the bibref of the properties in the ssoCard of SSOs. The whole set of bibliographic references of the articles from which the data are derived is also available in bibTeX, JSON, or PDF format.
