Abstract:
The ESO-Spitzer Imaging extragalactic Survey (ESIS) is the optical
follow up of the Spitzer Wide-area Infra-Red Extragalactic survey
(SWIRE) in the ELAIS-S1 region of the sky. We present VIMOS I and z
band imaging belonging to the ESIS survey. A total of ∼4 square
degrees were targeted in I and ∼1 in z. Accurate data processing
includes removal of fringing, and mosaicking of the complex observing
pattern. Completeness levels and photometric uncertainties are
estimated through simulations. More than 300000 galaxies have been
detected in the I band and ∼50000 in the z band. Object coordinates
are defined within an uncertainty of ∼0.2" r.m.s., with respect
to GSC 2.2. We reach a 90% average completeness at 23.1 and 22.5mag
(Vega) in the I and z bands, respectively.

Global Notes:
Note (G1): SExtractor flags (see Bertin 1998, SExtractor User's Guide v2.0)
are coded as a sum of powers of 2:
1 = The object has neighbors, bright and close enough to
significantly bias the photometry, or bad pixels (more
than 10% of the integrated area affected).
2 = The object was originally blended with another one.
4 = At least one pixel of the object is saturated (or very close to).
8 = The object is truncates (to close to an image boundary).
16 = Object's aperture data are incomplete or corrupted.
32 = Object's isophotal data are incomplete or corrupted.
64 = A memory overflow occurred during deblending.
128 = A memory overflow occurred during extraction.
