We have developed a dedicated software to perform data reduction, mosaicking and source detection on the BAT survey data. We analyzed the BAT dataset in three energy bands (14-150keV, 14-30keV, 14-70keV), obtaining a list of 962 detections above a significance threshold of 4.8 standard deviations. The identification of the source counterparts was pursued using three strategies: cross-correlation with published hard X-ray catalogues, analysis of field observations of soft X-ray instruments, cross-correlation with the SIMBAD database. The survey covers 90% of the sky down to a flux limit of 2.5x10-11erg/cm2/s and 50% of the sky down to a flux limit of 1.8x10-11erg/cm2/s in the 14-150keV band. We derived a catalogue of 754 identified sources, of which ∼69% are extragalactic, ∼27% are Galactic objects, ∼4% are already known X-ray or gamma ray emitters whose nature has not been determined yet. The integrated flux of the extragalactic sample is ∼1% of the Cosmic X-ray background in the 14-150keV range. Description: The catalogue contains the 754 sources detected and identified in the first 39 months of BAT survey data. It include the BAT position, together with the offset with respect to the identified counterpart, the detection significance, the flux in the 15-150keV band (evaluated assuming a Crab-like spectrum), the hardness ratio in the [30-150]/[15-30] bands and the source luminosity, together with the counterpart redshift.

Note (1): Calculated assuming a Crab-like spectrum Note (2): The hardness ratio is evaluated only when the source is detected both in the 15-30keV band and in the 15-150keV band. Note (4): If the source is not detected in the 14-150keV band, the flux is calculated in the largest available band and extrapolated in the 14-150keV band. The band is 1=14-150keV, 2=14-30keV, 3=14-70keV Note (5): Identification strategy flag as follows: a = cross-correlation with published hard X-ray catalogues b = analysis of field observations of soft X-ray instruments c = cross-correlation with the SIMBAD databases.
