\caption{An overview of the models for the selection effects used to generate simulated observations of simulated \obs{}, for the six major datasets discussed in Sects.~\ref{section:adonisobservations} to~\ref{section:hipparcosobservations}. The {\em sample bias}, resulting from the choice of the sample alone, includes the observer's choice and the brightness constraint. All other constraints result from the properties of the telescope, detector, atmospheric conditions, and confusion with background stars, and are in this paper referred to as the {\em instrument bias}. For a detailed description of the constraints mentioned in this table we refer to Sect.~4.5 of \cite{kouwenhoventhesis}. \label{table:sos_biases}}
