We report the detections of new high energy sources from the
Swift Burst Alert Telescope (BAT) hard X-ray survey, and subsequent follow-up
observations with the X-ray Telescope (XRT). The BAT survey covers the
15-200 keV band, and the time range Dec 2004 - Mar 2005. Sky coverage
was not uniform, so the survey is not yet complete for the full sky.
The sources reported in the table below are >5.5 sigma BAT
detections which are either previously unknown gamma-ray sources;
previously known sources which were previously unknown to be gamma-ray
emitters; or improved positions for previously known gamma-ray
emitters. The original BAT-only positions are accurate to within ~3
arcmin (90%). Typical 15-200 keV fluxes are half to a few mCrab.
In all cases, the BAT detections were also detected in follow-up
observations by the XRT in the 0.5-10 keV band. XRT positions are
accurate to within 3-4 arcsec after applying the new boresight correction
(Moretti et al. 2005, astroph/0511604; see XRT error radius in arc seconds
["ER"] column below).
The sources are identified by their Swift name and position, followed
by their likely identification and classification, where appropriate.
The table of results is in ATEL#669.
