- 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
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 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 is the rms error (per observation) in mmag. - Table 4: Apsidal motion parameters for SW CMa 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.
