Abstract:
We present the final analysis of the European Large Area Infrared
Space Observatory (ISO) Survey (ELAIS) 15-µm observations, carried
out with the ISO Camera (ISOCAM) instrument on board the ISO.
The data-reduction method, known as the Lari Method, is based on a
mathematical model of the behaviour of the detector and was
specifically designed for the detection of faint sources in ISOCAM/ISO
Photopolarimeter (ISOPHOT) data. The method is fully interactive and
leads to very reliable and complete source lists.
The resulting catalogue includes 1923 sources detected with
signal-to-noise ratio of >5 in the 0.5-100mJy flux range and over an
area of 10.85deg2 split into four fields, making it the largest
non-serendipitous extragalactic source catalogue obtained to date from
the ISO data.

Note (1): Astrometric error is determined by
σtot=sqrt[σs+g2+σp2]
Note (2): Photometric error is determined by
[(DeltaS)/S)]2=Delta(fs/f0)2+(σmap/fs)2
=Delta(fs/f0)2+(1/(S/N))2
Note (3): Optical ID as follows:
G = galaxy
S = star
U = unidentified source
Note (4): Aperture flag means the following:
0 = sources whose flux was estimated through autosimulation
1 = sources on which aperture photometry was preferred
