INTEGRAL source IGR J16562-3301 --- a new BL Lac object
Abstract
The accurate position of the hard X-ray source IGR J16562-3301/SWIFT J1656.3-3302 (Okajima et al. 2006, ATel #799, Krivonos et al. 2007, astro-ph/0701836) was determined earlier by Tueller et al. (2006, ATEL #835) using SWIFT/XRT observation of this field. We found that more accurate position of this source can be derived from the same data when the systematics of SWIFT/XRT astrometry is corrected using the other two bright X-ray sources identified with relatively bright optical stars.
