\caption{Results of the photometric study for stars in the Galactic anticentre direction.
Frequencies in \cd\ are shown for the Hipparcos, OSN and ASAS-3 datasets. The "$-$'' 
stands for stars for which a short-period analysis could not be performed. 
The "*'' stands for stars that were not observed with the instrument. 
The "**'' stands for stars that are saturated in the ASAS-3 database.
The "var'' stands for stars showing short-term variability but not periodicity. 
The "no var'' stands for stars that do not show short-term variations at the detection level of the instrument. The "?'' stands for frequencies that are uncertain. For details, see text. 
In the last column some complementary indications and/or frequencies detected by other authors are given: (1)~stars included in the ASAS-3 catalogue of variable stars \citep{pojmanski02};
(2)~\citet{neiner05b}; (3) \citet{hubert98}; (4) \citet{gutierrez07}; (5) \citet{lynds60};
(6) \citet{percy02}.}\label{table:resultados:anti}
