We report on further 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). For previously reported sources and an explanation of the BAT survey observing campaign are given by Tueller et al. (ATEL #668, ATEL #669).

In the table below, the sources are identified by their Swift/BAT name and XRT localized position, followed by their likely identification and classification, where appropriate. A full Swift/XRT name is given in the case where no previously identified source is consistent with the XRT position. The original BAT-only positions are accurate to within ~3 arcmin (90%). The XRT 90% containment error radius for each localization is given in arc seconds in the "ER" column below. These positions are calculated using the latest XRT boresight correction (e.g. Moretti et al., 2005).

(1) - Identification is the best candidate, but large (3.6') distance from BAT position makes this uncertain.
(2) - Error circle consistent with B=17.0 optical source in the USNO catalogue
(3) - Reported emission up to 150 keV from BeppoSAX observations (Elvis et al., 2000)
Gal - Galaxy
Sy1 - Seyfert 1
Sy2 - Seyfert 2
QSO - Quasar
