Observing Notes
Harold Corwin
[See NGC 3398 for the whole explanation]
... Finally, the identity of the two IC objects in the area -- IC 644 and IC 646 -- is unambiguous. While Swift's positions are often none too good, they are at least adequate in this case. The offset in RA is about 12 time-seconds for both, while the declinations are within a minute of arc. IC 644 turns out to be identical to NGC 3398, while IC 646 is MCG +09-18-039.
