and UV counterparts in the USNO-B1.0 catalogue ($I$, $R$ and $B$~bands) and \swift/UVOT detector ($V$, $U$, $UVW1$, $UVM2$, and $UVW2$~bands). The $B$~magnitudes are those obtained from the USNO-B1.0 catalogue, except where indicated. The long dashes indicate the absence of corresponding

$^\ddagger$ Values averaged over multiple pointing; $^\star$ there are two possible USNO-B1.0 sources in the XRT error circle. This is the closest to the IR~source; $^\dagger$ the UVOT positional accuracy is dominated by  a statistical uncertainty of 1.1\arcsec; $^\diamond$~$B$ magnitude obtained from \swift/UVOT; $^\ast$ average value obtained with {\tt uvotsource}.
