There is a long tradition of publishing minima/maxima times of variables in IBVS. We find errata published for a considerable number of papers falling to this category. As it is a tedious work for the Editors or the referee to check each published minimum, we have decided to require additional information from the authors.
Henceforth we ask authors to find a suitable ephemeris for each given star, compute the O-C values by this ephemeris for their observations, and if possible, compare them with values listed in databases, such as the "UP-TO-DATE LINEAR ELEMENTS OF ECLIPSING BINARIES" by J.M. Kreiner (http://www.as.up.krakow.pl/ephem/), the "Eclipsing Binary O-C Files" by Bob Nelson (http://www.aavso.org/observing/programs/eclipser/omc/), or the "Lichtenknecker-Database of the BAV" (http://www.bav-astro.de/LkDB/index.php?lang=en).
We ask authors to submit a simple ASCII version of their LaTeX table, with two additional columns, containing the O-C value, and an ephemeris reference. An additional table could be used to expand these references.
These additional tables will not be published, they serve solely for the purpose of quality control.
