Asteroseismology of the Cephei star Eridani - IV. The 2003-2004 multisite photometric campaign and the combined 2002-2004 data

Abstract

We report on the second multisite photometric campaign devoted to Eridani ( Eri). The campaign, carried out from 2003 September 11 to 2004 February 16, was very nearly a replica of the first campaign, 2002-2003: the five telescopes and photometers we used were the same as those in the first campaign, the comparison stars and observing procedure were identical, and the numbers and time baselines of the data were comparable.
