is a group of astronomical quantities that describes tables at the level of astronomical theory. can be shared by several tables across different traditions. Broadly speaking, there are two kinds of parameters: explicit parameters that are directly read off the table (e.g., the maximum value(s)); and implicit parameters that need to be retrieved from the computationally (e.g, solar eccentricity). In some cases, these explicit or implicit parameters are only significant in groups.In other instances, however, parameters can be independently significant.
