Abstract

This paper presents the I-band data obtained by the ESO Imaging Survey (EIS) over two patches of the sky, 6 square degrees each, centered at α ∼ 5h40m, δ ∼ -24°50m and α ∼ 9h50m, δ ∼ -21°00m. The data are being made public in the form of object catalogs and, photometrically and astrometrically calibrated pixel maps. These products together with other useful information can be found at "http://www.eso.org/eis". The overall quality of the data in the two fields is significantly better than the other two patches released earlier and cover a much larger contiguous area. The total number of objects in the catalogs extracted from these frames is over 700,000 down to I ∼ 23, where the galaxy catalogs are 80% complete. The star counts are consistent with model predictions computed at the position of the patches considered. The galaxy counts and the angular two-point correlation functions are also consistent with those of the other patches showing that the EIS data set is homogeneous and that the galaxy catalogs are uniform.
