Description:
The data files includes photometric observations of the eclipsing
binary system IU Aurigae. New photometric observations were made on 13
nights at the Ankara University Observatory (AUO) in 1997/1998 by
using a 30cm Cassegrain-Maksutov telescope. The detector was a
single-channel, uncooled SSP-5 photometer equipped with Hamamatsu
R1414 photomultiplier tube.
Observational standard errors determined from check star (HD 35633 =
SAO 58053) measurements are 0.014mag, 0.012mag, and 0.018mag in U, B,
and V filters, respectively. A total of 966, 959, 947 original data
and of 118, 117, 117 reduced (averaged) data points is included for
each UBV filters, respectively.
