Description
Table 1 contents 1313 simultaneous measurements collected in each of the four uvby colours of the Stromgren photometric system for the semi-detached Algol-type eclipsing binary system AB Cas, where the primary component is a Delta Scuti-type pulsator. The data are magnitude differences (Du, Dv, Db, Dy, D(b-y), Dm1, Dc1) of the variable star minus comparison star in the standard system versus Heliocentric Julian Date. The comparison star is HD 14836. The origin in time is the Julian Day 2451108. The observations were carried out by the authors through the years 1998 and 1999 using the 0.90m telescope at Sierra Nevada Observatory, Spain. This telescope is equipped with a six-channel uvby-H{beta} spectrograph photometer for simultaneous measurements in uvby or in the narrow and wide H{beta} channels, respectively.
