Each CCD of the mosaic is named from \textit{a} to \textit{h}, starting from the upper left corner and going clockwise to the bottom left corner. \\ $^f$ The variability flag column catalogues all objects from their variation properties. The possibilities are: non-variable (NonV), irregular variable (IV), periodic variable (PV), possible periodic variable (PPV) and possible eclipsing system (PES). \\ $^g$ 2MASS identification number. \end{table}
