\caption{Differential LTPV photometry of HD~168112. The quoted magnitudes and 1-$\sigma$ dispersions correspond to the difference A~5020~$-$~B~5020 (where A~5020 is the magnitude of HD~168112 and B~5020 that of HD~168135). The first column yields the code of the telescope~+ instrument configuration (see Manfroid et~al. \cite{manfroid}) and the second column indicates the number of data points for each set-up.}\label{tab-ltpv}
