+"""Basic parameters and data
+
+This space reads parameters from a parameter file.
+The parameters are then be referenced in other parts of the model.
+
+There are a few types of parameters depending on the variability of their values.
+Constant parameters have values that are constant anywhere in the model.
+Run parameters can have different values for different runs.
+Space parameters can have different values for different product spaces.
+These three types of parameters are called fixed parameters,
+because they have fixed values in each product space.
+
+Product parameters are specific to individual product spaces.
+Each product space has product parameters.
+The values of product parameters vary by "product_id" and "plan_id"
+defined for the product space.
+Product parameters are appended to the model point table for the product space
+in :func:`~appliedlife.IntegratedLife.ModelPoints.model_point_table_ext`.
+
+Other spaces reference this space as ``base_data`` as a convention.
+
+In addition to the parameters, this space also reads surrender charge tables
+to be used in other spaces.
