Abstract:
We present the catalogue of X-ray sources detected by the two Wide
Field Cameras (WFCs) in complete observations on board BeppoSAX during
its 6 years of operational lifetime, between April 1996 and April
2002. The BeppoSAX WFCs were coded mask instruments sensitive in the
2-28keV energy band with a 40x40 square degree fields of view,
pointing in opposite directions and perpendicularly to the BeppoSAX
Narrow Field Instruments (NFI). The WFCs were usually operated
simultaneously to NFI observations, each lasting up to several days.
WFCs observed thus the entire sky several times with a typical
sensitivity of 2 to 10mCrab.
A systematic analysis of all WFC observations in the BeppoSAX archive
has been carried out using the latest post-mission release of the WFC
analysis software and calibrations. The catalogue includes 253
distinct sources, obtained from a total sample of 8253 WFC detections.
We describe the basic statistical properties of the sample and present
a six-year history of two celestial calibration X-ray sources.

Note (1): Detection notes as follows:
h = detected with the highest snr in a softed band, 2-5.5 or
2-3.2keV with respect to the catalogue reference 2-8keV band.
i = detected with the highest snr in a harder band, 8-19, 5.5-11, 6-13
or 11-19keV with respect to the catalogue reference 2-8keV band
j = detected with the highest snr in a larger band, 2-19 or 2-26keV
band, with respect to the catalogue reference 2-8keV band
k = source detected in the first processing stage only
Note (2): The position error is the mean 99% X, Y error added in quadrature
to a systematic error of 1.3'.
Note (3): 2-10keV flux and error in units of 10-11erg/s/cm2
(10-14W/m2).
Note (4): The flux weighted mean among all the detections of a source
and its standard deviation in units of 10-11erg/s/cm2^
(10-14W/m2).
Note (5): The 2-10keV flux reduced Chi2 among all source detections.
Note (6): The maximum and minimum 2-10keV flux among all source detections.
