Description:
The catalog represents the final band-merged European Large-Area ISO
Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175µm, and the
associated data at U, g', r', i', Z, J, H, K and 20cm.
Details about the origin of the survey, the observations, data
reduction and optical identification are described in the paper. In
addition to fluxes in the radio, infrared and optical passbands,
spectroscopic redshifts are tabulated, where available. For the N1 and
N2 areas, the Isaac Newton Telescope ugriz Wide Field Survey permits
photometric redshifts to be estimated for galaxies and quasars.

Note (1): For merged sources, in order of preference
15µm, 20cm, 6.7, 90, 175µm
Note (3): The 6.7µm reliability flags have the following meaning:
2 = high reliability
3 = medium reliability
20 = not specified in the text (may be a typo)
Note (4): Flag 1 has the following meaning:
1: if radio flux force-merged (15µm and radio positions within 5")
2: if 6.7µm flux force-merged
3: if 90µm association is not the most likely, where there are
multiple associations
4: if 175µ association is not the most likely, where there are
multiple associations
5: if second-best optical association for 15µm has been preferred
on basis of radio position
6: if source has an IRAS association
7: if 1 and 6 both set
8: if 3 and 4 both set
9: if 1 and 8 both set, or 4 and 5 both set
Note (5): Flag 2 has the following meaning:
1: if source falls in gaps between WFS chips, so no optical data,
2: if source falls near edge of WFS chip, so photometry may be
unreliable
3: if source has multiple optical counterparts
4: if source is blank in optical (i.e. no optical counterpart with
probability of association >0.7 within specified search radius)
6: if there is an association in NED
7: if association is bright star
8: if flags 1 and 7 set
9: if flags 3 and 7 set
Note (6): Photometry references:
1: if J,H,K magnitudes from 2MASS, Cat. II/246
2: if J, K magnitudes from Vaisanen et al (2002MNRAS.337.1043V 2002MNRAS.337.1043V)
3: if K magnitudes from Rigopoulou et al (2004, in preparation)
4: if K magnitude from Pozzi et al (2003MNRAS.343.1348P 2003MNRAS.343.1348P)
5: if K magnitude from Sajina et al (2003MNRAS.343.1365S 2003MNRAS.343.1365S)
Note (7): Reliability of optical association:
The probability that an optical object of magnitude m is the true
counterpart of a source with an error ellipse defined by ist major
(s1) and minor (s2) axis, separated by a distance r is given by
L = [Q(m)exp(-r2/2)]/[2π.s1.s2.N(m)],
where Q and N are the magnitude distributions of the sources and
objects respectively. The reliability of such identification is
Rj = Lj/[{Sum}iLi + (1-Q)]
Note (8): The photometric SED type is defined as follows:
1: E galaxy
2: Sab galaxy
3: Sbc galaxy
4: Scd galaxy
5: Sdm galaxy
6: starburst galaxy
7: AGN 1 (fig. 9 of paper)
8: AGN 2 (fig. 10 of paper)
Note (10): The classes are defined as follows:
1: (spiral) galaxy
2: emission-line, starburst
3: absorption line, early type galaxy
4: AGN
5: Sy1
6: Sy2
7: star
8: liner

Note (12): The IR SED type has the following values:
1 = cirrus
2 = M82-starbust
3 = Arp220-starbust
4 = AGN dust torus
5 = cooler cirrus
6 = 2+4
