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-Hβ spectrograph photometer for
simultaneous measurements in uvby or in the narrow and wide Hβ
channels, respectively.
