Just another stupid question from the Brain-Dead here...
When I look to the resources available on the net for the Artemis Corona on Venus, I can cite supposedly scientific sites which contradict each other with differing
dimensions for this feature on the surface of Venus.

Can someone tell me how one can resolve these contradictions please? I really do wish to know, and thus far my inquiries to some of the following sites have been
completely ignored.
The first three sites describe the Artemis Corona as having a diameter of 2600 kilometers...
The next two define the same feature as having its diameter as 2100 kilometers...

How does one arrive at the truth here?
Confused (as usual) Bob

I was about to suggest that the NASA link http://photojournal.jpl.nasa.gov/catalog/PIA00101 would probably be correct but this link http://planetarynames.wr.usgs.gov/jsp/F ... ture=60570 seems to suggest that this data was adopted by the IAU so this is probably correct assuming that there are not any typos. Just an opinion though.

I appreciate that Steve, but we have two government bodies above disseminating two different sets of "facts." Which one should I believe? I have e-mailed with no response as yet.
Thanks, Bob
