Abstract:
We present the X-ray source catalogues for the XMM surveys of the 3-h
and 14-h (also known as the Groth Strip) Canada-France Redshift Survey
fields (0.5-10keV flux range ∼2x10-15-10-13erg/cm2/s). We use a
subset of the XMM sources, which have Chandra positions, to determine
the best method of obtaining optical identifications of sources with
only XMM positions. We find optical identifications for 79 per cent of
the XMM sources for which there are deep optical images. The sources
without optical identifications are likely to be optically fainter and
have higher redshifts than the sources with identifications. We have
estimated 'photometric redshifts' for the identified sources,
calibrating our method using ∼200 galaxies in the fields with
spectroscopic redshifts. We find that the redshift distribution has a
strong peak at z∼0.7.

Note (1): HR=(N(H)-N(S))/(N(H)+N(S))
where N(H) and N(S) are the counts observed for a source in the hard
(2-10keV) and soft (0.5-2keV) bands, respectively, after correction
for vignetting. Higher values indicate a harder spectrum.

Global notes:
Note (G1): Notes have the following meaning:
- = lies outside CFDF map
c = lies within Chandra map (X-ray property)
d = d = detected by Chandra (X-ray property)
e = extended source (X-ray property)
q = known QSO
s = object with a stellar profile
* = in 3h, sources 7 and 19 are in fact the same source split into
two owing to its lying on a PN chip gap
