$^a$ Identification numbers from Hillenbrand (\cite{Hill97}) for numbers below 10~000; from H2002 for numbers between 10~000 and 11~115, and from this study for identification numbers above 20~000. \\ 
$^b$ $I$ magnitude.  \\
$^c$ Photometric I magnitude error.  \\
$^d$ Number of data points considered in the time series analysis. \\
$^e$ CCD identification. 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.
