Notes. Optical source coordinates are extracted from the 2MASS catalog, if not indicated otherwise, and have an accuracy better than 01. Soft X-ray coordinates are extracted from XRT, Chandra or ROSAT observations. If not indicated otherwise, source X-ray coordinates were obtained from XRT data. The source is outside BAT 90% and 99% error box, but it is associated with a 2MASS source in the 70 month BAT catalogue.

(=)

The reported optical coordinates are obtained from USN-A2.0 catalogue.

(C)

The reported X-ray coordinates are obtained from Chandra data.

(R)

The reported X-ray coordinates are obtained from ROSAT bright catalogue.

(+)

This source is outside BAT 90% error box, but inside the 99% one.

(-)

This source is at the edge of BAT 90% error box, inside the 99% one.
