I've never seen a full map like that...but there seem to be some obvious errors, for instance, that map shows Corellia, Selonia, Talus, and Tralus in separate, fairly widely separated systems. Established EU is that these planets are in the same system.
More information to add to the mix is the actual exchange Han and Leia have while looking at the Falcon's monitor. As I recall, it was somewhat like:
"Where are we?"
"Anoat System? Not much there."
"Nah...wait, this is interesting...Lando!"
"The 'Lando' System?"
"...Bespin's pretty far, but I think we can make it."
So either Bespin is in the Anoat system, or the Falcon travelled from Anoat to Bespin sub-light (the hyperdrive was broken the whole time).
