 \caption{\label{t1}Journal of observations of TT Ari:
The ``legend Julian date LJD'' (integer part of the Julian date for the beginning of the night); number of observations $n$; time of the begin $t_{\rm b}$ and end $t_{\rm e}$ of observations (for the many nights, the observations ended on the next integer JD); duration of the run $t_{\rm e}-t_{\rm b}$; magnitude range for individual data points $m_{\rm max}$, $m_{\rm min}$;
nightly mean $\bar{m}$ and it's accuracy estimate $\sigma(\bar{m})$;
rms deviation of the single observation from the mean $\sigma(m)$;
exp -- time resolution in seconds. All moments of time are expressed in (BJD-2~400~000).
