We provide X-ray counterparts for unidentified Swift/BAT sources in the 105 month catalogue (Oh et al. 2018, ApJS in press).
They were found by cross-correlating the list of U1,U2 and U3 sources with the ROSAT Bright (RASSBSC, Voges et al. 1999, A&A, 349, 389) and XMM-Newton Slew (XMMSlew, Saxton et al. 2008, A&A, 480, 611) catalogues and optically identified as reported in Atel #11340.
For U3 sources, we find 15 associations listed below.
For SWIFT J1105.4+0200 two possible X-ray counterparts were found; XRT data indicate that both are viable associations as both are detected above 3 keV.
For 2 sources we retrieved and analysed 6dFGS spectra: 2MASS J19095128+4058466 is classified as an AGN candidate in Simbad while XMMSL2 J190921.2+011225
is most likely of galactic origin being located close to the galactic plane and displaying WISE colours which are not typical of an AGN.
