All Tables

Table 1: rms errors of the magnitude differences (instrumental system) between the comparison stars in units of 0.1 mmag. N is the total number of magnitude differences.
Table 2: New photometric data for the eclipsing binaries and the comparison stars. For the eclipsing binaries, the ${\it uvby}\beta$ information is the mean values outside eclipses, see also Fig 1. N is the total number of observations used to form the mean values, and $\sigma$ is the rms error (per observation) in mmag. See also Table 3.
Table 3: Published photometric data for the eclipsing binaries and the comparison stars. N is the total number of observations used to form the mean values, and $\sigma$ is the rms error (per observation) in mmag.
Table 4: Apsidal motion parameters for SW CMa derived from the photoelectric times of minima.
Table 5: Apsidal motion parameters for V636 Cen derived from the photoelectric times of minima.
Table A.1: Times of primary minima for AD Boo. O-C values are calculated for the ephemeris given in Eq. (1) assuming a circular orbit. Observing methods are: PG photographic; V visual; PE photoelectric or CCD. Times marked with an asterisk were published after we completed the ephemeris calculations; including them makes no significant changes.
Table A.2: Times of secondary minima for AD Boo. See Table A.1 for details.
Table A.3: Times of primary (P) minima of HW CMa. O-C values are calculated for the ephemeris given in Eq. (2).
Table A.4: Times of primary (P) and secondary (S) minima of SW CMa. O-C values are calculated for the apsidal motion ephemeris given in Table 4. Times given in brackets have not been used for the ephemeris determination.
Table A.5: Times of primary (P) and secondary (S) minima for V636 Cen. O-C values are calculated from the apsidal motion parameters given in Table 5.
Table A.6: Times of primary (P) and secondary (S) minima for VZ Hya. O-C values are calculated for the ephemeris given in Eq. (5) adopting a circular orbit. Observing methods are: PG photographic; V visual; PE photoelectric or CCD. Times marked with an asterisk were published after we completed the ephemeris calculations; including them makes no significant changes.
Table A.7: Times of primary minima for WZ Oph. O-C values are calculated for the ephemeris given in Eq. (6) assuming a circular orbit. Observing methods are: PG photographic; V visual; PE photoelectric or CCD. Times marked with an asterisk were published after we completed the ephemeris calculations; including them makes no significant changes.
Table A.8: Times of secondary minima for WZ Oph. See Table A.7 for details.
