\item[Note:] For each object, identified by its number, the total number of observations is shown, as well as the number of observations with nominal accuracy less than $0.01$, $0.02$, $0.03$, $0.04$, $0.05$ mag, respectively. The last column gives the average error $\langle\sigma\rangle$ of
the observations. Bold characters in the Table are used to indicate objects with data for which the nominal requirements for successful inversion as derived from Fig.~\ref{testerrore} are met.
