\caption{Characteristics of the multi-sinusoidal fit of individual
runs of observations of BG CMi. The flux is expressed in units of
$10^{-15}$~erg~s$^{-1}$~cm$^{-2}$~\AA$^{-1}.$ The calibration in~$V$
has been made using the magnitude of the comparison star. For~$R$,
the standard magnitude is unknown and has been arbitrarily set to
zero. This makes values of intensity to be apparently large. They
may be calibrated after further determination of the $R$~magnitude
of the comparison star. For bad phase distribution caused by an
incomplete coverage of the period in the first two runs, the
values are highly biased and should not be taken for further
analysis. Such biased or statistically insignificant values are
marked by a semi-column ":''.\label{tab2}}
